Music City is having a sale on compact discs. The regular price of $14.00 is decreased by 20%. What is the sale price?
Option 1: The sale price is $11.20.
Option 2: The sale price is $2.80.
To solve this problem, we need to find the sale price after the 20% discount.
Step 1: Calculate the amount of the discount.
To find 20% of $14.00, multiply $14.00 by 0.20:
$14.00 x 0.20 = $2.80
Step 2: Subtract the discount from the regular price.
Subtract $2.80 from $14.00:
$14.00 - $2.80 = $11.20
Therefore, the sale price of the compact disc after a 20% discount is $11.20.
To find the sale price, you need to calculate 20% of the regular price and then subtract that amount from the regular price.
Step 1: Calculate 20% of $14.00
To calculate 20% of a number, you can multiply the number by 0.20. So, 20% of $14.00 is:
$14.00 * 0.20 = $2.80
Step 2: Subtract the calculated amount from the regular price
To find the sale price, you need to subtract the calculated amount ($2.80) from the regular price ($14.00). So:
$14.00 - $2.80 = $11.20
Therefore, the sale price of the compact disc is $11.20.

A handbag originally cost $85.00. Now it is priced at $68.00. What is the percent of decrease?
To find the percent of decrease, we need to calculate the difference between the original price and the new price, then divide that difference by the original price and multiply by 100.
Step 1: Calculate the difference between the original price and the new price.
$85.00 - $68.00 = $17.00
Step 2: Divide the difference by the original price.
$17.00 / $85.00 = 0.20
Step 3: Multiply the result by 100 to get the percentage.
0.20 * 100 = 20
Therefore, the percent of decrease is 20%.

Find the total purchase price if a pair of shoes originally costs $35.00 and are on sale for 25% off. The sales tax is 7%. Round the answer to the nearest cent. (Calculate the sales tax on the original price and then add it to the discounted price of the shoes.)
$Blank Space __________
To solve this problem, we need to calculate the discounted price of the shoes and then add the sales tax to find the total purchase price.
Step 1: Calculate the discounted price of the shoes.
To find the discounted price, we can multiply the original price by the discount percentage and subtract it from the original price.
Discount amount = 25% of $35.00 = 0.25 * $35.00 = $8.75
Discounted price = Original price - Discount amount = $35.00 - $8.75 = $26.25
Step 2: Calculate the sales tax amount.
To find the sales tax amount, we can multiply the discounted price by the sales tax percentage.
Sales tax amount = 7% of $26.25 = 0.07 * $26.25 = $1.8375 (rounded to the nearest cent, it becomes $1.84)
Step 3: Calculate the total purchase price.
The total purchase price is the discounted price plus the sales tax amount.
Total purchase price = Discounted price + Sales tax amount = $26.25 + $1.84 = $28.09
Therefore, the total purchase price, rounded to the nearest cent, is $28.09.

The Bell family's bill at a restaurant totaled $34.62. How much tip should they leave for their waiter? The standard for tipping is 15% of the total bill. Round the answer to the nearest cent.
To find the tip amount, we can multiply the total bill by the tip percentage.
Step 1: Calculate the tip amount.
Tip amount = 15% of $34.62 = 0.15 * $34.62 = $5.193 (rounded to the nearest cent, it becomes $5.19)
Therefore, the Bell family should leave a tip of $5.19.

Lori makes $64,000 each year as an accountant. At Christmas she was given a 12% bonus. How much was her bonus?
To find Lori's bonus, we can multiply her annual salary by the bonus percentage.
Step 1: Calculate the bonus amount.
Bonus amount = 12% of $64,000 = 0.12 * $64,000 = $7,680
Therefore, Lori's bonus was $7,680.

Of 140 people surveyed, 60% prefer vanilla ice cream over chocolate ice cream. How many people prefer vanilla ice cream?
To find the number of people who prefer vanilla ice cream, we can multiply the total number of people surveyed by the percentage who prefer vanilla ice cream.
Step 1: Calculate the number of people who prefer vanilla ice cream.
Number of people who prefer vanilla ice cream = 60% of 140 people = 0.60 * 140 = 84
Therefore, 84 people prefer vanilla ice cream.
Marco makes $36,000 a year. If he receives a 5% raise, how much more money will he be earning each year?
To find how much more money Marco will be earning each year with a 5% raise, we can multiply his current salary by the percentage increase.
Step 1: Calculate the raise amount.
Raise amount = 5% of $36,000 = 0.05 * $36,000 = $1,800
Therefore, Marco will be earning $1,800 more each year with the 5% raise.

In 1970, a desktop calculator sold for about $100.00. Today the same type of calculator sells for as little as $25.00. What is the percent of decrease in the cost of desktop calculators?
To find the percent of decrease in the cost of desktop calculators, we need to calculate the difference between the original price in 1970 and the current price, then divide that difference by the original price and multiply by 100.
Step 1: Calculate the difference in price.
Difference in price = Current price - Original price = $25.00 - $100.00 = -$75.00
Step 2: Divide the difference by the original price.
Percent of decrease = (Difference in price / Original price) * 100 = (-$75.00 / $100.00) * 100 = -75%
Therefore, the percent of decrease in the cost of desktop calculators is 75%.

Jennifer is a 75% free-throw shooter. If she shot 44 free-throws this year, how many did she make?
To find how many free throws Jennifer made, we can multiply the total number of free throws by her shooting percentage.
Step 1: Calculate the number of free throws made.
Number of free throws made = Shooting percentage * Total number of free throws
Number of free throws made = 75% * 44 = 0.75 * 44 = 33
Therefore, Jennifer made 33 free throws.
