CAN SOMEONE HELP ME WITH A PROJECT? I'll give 500 Points and Brainliest. WRONG ANSWERS WILL BE DELETED. Directions:

Complete each task, reading the directions carefully as you do. For these tasks, round all decimals to the nearest hundredths place or to the nearest cent.

You will be graded on the work you show, or your solution process, in addition to your answers. Make sure to show all your work and to answer each question as you complete the task. Type all of your work into this document so you can submit it to your teacher for a grade. You will be given partial credit based on the work you show and the completeness and accuracy of your explanations.
Now let’s get started!

Step 1: Solving real-world problems that involve finding a percent of a number

a) Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%. How much is Isaac’s total bill? Show your work. (2 points)

b) If Isaac uses a coupon entitling him to a 25% discount off the purchase price before tax, how much will his bill be? Assume that a 7% sales tax is applied to the discounted price. Using words, explain how you found the discounted price. (3 points)

c) The shoe store’s clerks are paid on commission. If the clerk receives a 12% commission on total purchase amounts before tax is applied, how much would the commission be for Isaac’s purchase with and without a coupon? (2 points)

Step 2: Estimating with percents

a) Isaac and his sister plan to surprise their parents by buying them each a pair of shoes. They agree that Isaac will pay 68% of the price since he receives a greater allowance. Use an estimation strategy to determine how much Isaac will pay if the total bill is $97.65. Show the step-by-step process you used to solve the problem. (2 points)

Step 3: Solving real-world problems that involve markups

a) A local shoe store buys shoes at a wholesale price and then marks them up 80% to calculate the retail price. The wholesale price varies, depending on the quantity of shoes purchased. (2 points)
Quantity

0-20 pairs

21-40 pairs

41-60 pairs

61-80 pairs

81 or more pairs

Wholesale Price
(per pair)

$25.00 each

$23.00 each

$21.00 each

$19.00 each

$17.00 each

Write an equation that could be used to find the retail price for each range. How do you know the equation will work consistently for each range? (2 points)

b) Using the formula from part a, calculate the retail price for each quantity range. (2 points)

Step 4: Solving simple interest problems that involve finding a total amount

a) The shoe store manager borrowed $17,000.00 from the bank to purchase 1000 pairs of shoes. The bank charges a simple interest rate of 5% per year on a loan to a business. If it takes 3 years to pay back the loan and interest, what is the total amount of interest that the shoe store will pay? (2 points)

b) What is the total amount, including interest, that the shoe store must pay on the loan? (2 points)

c) How could you use estimation to determine if your answer is reasonable? Explain. (2 points)
