Hint: Calculate the tax AFTER finding the increased price
I am so sorry Ms. Sue! I still don't understand!
1A. 12.99*5%=12.99*.05=0.65 this is the sale tax
12.99 + 0.65= 13.64 is the price after tax
1B. 12.99*20%=12.99*0.2=$2.6 is discount
12.99 - discount= 12.99 - 2.6=10.39 is the price after discount was applied
10.39*5%=10.4*0.05=0.52 is the tax
10.39+.52=$10.91 is the price after discount with 5% tax
2A. 329.00*15%= 329.00*0.15=$49.35 this is the discount.
329 - discount = 329 -49.35=$279.65 discounted price
2B. 329*10%=329*0.1=32.9 is how much more the ipad will cost compared to the old price (increase in price). Now add it to the old price: 329 + 32.9=$361.9 is new price
361.9*10%=361.9*0.1=36.19 is a sale tax after change in price
361.9+36.19=$398.09 is the final price
Thanks! My teacher nearly said the same thing!
No need to apologize! I'm here to help you understand. Let's go through the questions step by step:
1. Price of the dolls: $12.99
A. Price of the dolls with a 5% sales tax:
To calculate the price of the dolls with the sales tax, you need to add the tax amount to the original price.
Step 1: Calculate the tax amount by multiplying the original price ($12.99) by the tax rate (5%):
Tax amount = $12.99 * 0.05 = $0.6495 (rounded to 2 decimal places)
Step 2: Add the tax amount to the original price to get the total price with tax:
Total price with tax = $12.99 + $0.6495 = $13.6395 (rounded to 2 decimal places)
So, the price of the dolls with a 5% sales tax is $13.64.
B. A discount of 20% is applied to the doll's original price of $12.99. What is the price of the dolls with the discount applied to $12.99 + 5% tax?
To find the price of the dolls after applying both the discount and the tax, you need to break it down into steps:
Step 1: Calculate the discount amount by multiplying the original price ($12.99) by the discount rate (20%):
Discount amount = $12.99 * 0.20 = $2.598 (rounded to 3 decimal places)
Step 2: Subtract the discount amount from the original price to get the discounted price:
Discounted price = $12.99 - $2.598 = $10.392 (rounded to 3 decimal places)
Step 3: Calculate the tax amount on the discounted price by multiplying the discounted price ($10.392) by the tax rate (5%):
Tax amount = $10.392 * 0.05 = $0.5196 (rounded to 4 decimal places)
Step 4: Add the tax amount to the discounted price to get the total price with the discount and tax:
Total price with discount and tax = $10.392 + $0.5196 = $10.9116 (rounded to 4 decimal places)
So, the price of the dolls with a 20% discount applied to $12.99 + 5% tax is $10.91.
2. Price of the iPad Mini: $329.00
A. Price of the iPad with a 15% discount:
To calculate the price of the iPad with a 15% discount, you follow a similar process as in the previous example:
Step 1: Calculate the discount amount by multiplying the original price ($329.00) by the discount rate (15%):
Discount amount = $329.00 * 0.15 = $49.35
Step 2: Subtract the discount amount from the original price to get the discounted price:
Discounted price = $329.00 - $49.35 = $279.65
So, the price of the iPad Mini with a 15% discount is $279.65.
B. During Christmas, the iPad Mini's price goes up 10%. There is also a sales tax of 10% added to the increased price.
Step 1: Calculate the increased price by multiplying the original price ($329.00) by the increase rate (10%):
Increased price = $329.00 * 0.10 = $32.90
Step 2: Add the increased price to the original price to get the total price after the increase:
Total price after increase = $329.00 + $32.90 = $361.90
Step 3: Calculate the tax amount on the increased price by multiplying the increased price ($361.90) by the tax rate (10%):
Tax amount = $361.90 * 0.10 = $36.19
Step 4: Add the tax amount to the increased price to get the final price including the increase and sales tax:
Final price = $361.90 + $36.19 = $398.09
So, the price of the iPad Mini after the 10% increase and 10% sales tax is $398.09.
