Riley needs to earn enough money to purchase a new jacket. The one he likes best is $49.99. His state sales tax is 7.25%. How much money does he need to earn? Round to the nearest dollar.
A. $54
B. $50
C. $82
D. $3.62
To find out how much money Riley needs to earn, we need to add the jacket price and the sales tax.
Sales tax = (Jacket price * Sales tax rate) = ($49.99 * 7.25%) = $3.62
So, Riley needs to earn $49.99 + $3.62 = $53.61.
Rounded to the nearest dollar, Riley needs to earn $54.
Therefore, the answer is A. $54.
Rafeal's family dinner costs $56.25. His dad wants him to leave a 35% tip. How much money should Rafeal provide as a tip? Round your answer to the nearest hundredth.
A. $75.94
B. $1.97
C. $35.00
D. $19.69
To calculate the tip amount, we need to multiply the cost of the meal by the tip percentage.
Tip amount = (Cost of meal * Tip percentage) = ($56.25 * 35%) = $19.69
Thus, Rafeal should provide a tip of $19.69.
Therefore, the answer is D. $19.69.
Jackson is treating his best friend to lunch for his birthday. They order two deluxe hamburgers and fries at $14.95 a plate and two large sodas at $3.49 each. Then as a birthday surprise, Jackson orders two pieces of chocolate cake at $7.95 each. Jackson knows that the tax is 8.21%. How much will Jackson's bill be with tax?
A. $26.39
B. $26.39
C. $28.56
D. $52.78
To calculate the total bill with tax, we need to add up the cost of the food items and then add the tax.
Cost of the two deluxe hamburgers and fries = 2 * $14.95 = $29.90
Cost of the two large sodas = 2 * $3.49 = $6.98
Cost of the two pieces of chocolate cake = 2 * $7.95 = $15.90
Total cost of the food items = $29.90 + $6.98 + $15.90 = $52.78
Tax amount = (Total cost of the food items * Tax rate) = ($52.78 * 8.21%) = $4.34
Total bill with tax = Total cost of the food items + Tax amount = $52.78 + $4.34 = $57.12
Rounded to the nearest cent, Jackson's bill will be $57.12.
Thus, the correct answer is D. $52.78.
Last year Jess earned 8.50 an hour at work. After a raise, she now earns 9.85 an hour. What is the percent change in her hourly wages? Round your answer to the nearest hundredth.
A. 0.1588%
B. 0.1371%
C. 13.71%
D. 15.88%
To calculate the percent change in Jess's hourly wages, we need to find the difference between her new wage and old wage, and then calculate that as a percentage of the old wage.
Change in hourly wage = New hourly wage - Old hourly wage = $9.85 - $8.50 = $1.35
Percent change = (Change in hourly wage / Old hourly wage) * 100 = ($1.35 / $8.50) * 100 = 15.88%
Rounded to the nearest hundredth, the percent change in Jess's hourly wages is 15.88%.
Thus, the answer is D. 15.88%.
Aatikah plans to buy books at a book fair. She thinks she will need $30.00 to purchase the books. She only spent $19.75. Find the percent error in her prediction. Round your answer to the nearest whole number.
A. 2%
B. 1%
C. 58%
D. 52%
To find the percent error in Aatikah's prediction, we need to calculate the absolute value of the difference between her predicted amount and the actual amount she spent, and then calculate that as a percentage of her predicted amount.
Predicted amount = $30.00
Actual amount spent = $19.75
Difference = Actual amount - Predicted amount = $19.75 - $30.00 = -$10.25
Absolute value of the difference = |-$10.25| = $10.25
Percent error = (Absolute value of the difference / Predicted amount) * 100 = ($10.25 / $30.00) * 100 = 34.17%
Rounded to the nearest whole number, the percent error in Aatikah's prediction is 34%.
Thus, the correct answer is none of the given options.
To calculate how much money Riley needs to earn, you need to add the cost of the jacket to the amount of sales tax.
First, calculate the amount of sales tax that needs to be added to the cost of the jacket:
Sales tax = (Cost of jacket) * (Sales tax rate)
Sales tax = $49.99 * 0.0725
Next, add the sales tax to the cost of the jacket:
Total cost = Cost of jacket + Sales tax
Total cost = $49.99 + (sales tax amount)
Now, you can calculate the total cost by substituting the values:
Total cost = $49.99 + ($49.99 * 0.0725)
After calculating, you will find that the total cost is approximately $53.72.
Since the question asks to round to the nearest dollar, the closest option is $54. Therefore, Riley needs to earn $54 (Option A) to purchase the new jacket.
