Part C: Every store emplyee gets an additional 10% off the already discounted price. If an employee buys an item with an original price of $40, how much will the employee pay?

Step-by-step explanation:

Part A

The discount offered is 30%. If the original price of a sweater is $40, then the discount on the sweater is

30/100 × 40 = $12

The cost of the sweater after the discount is

40 - 12 = $28

Part B

The discount on the shirts was 30%. The amount taken off the shirt is

30/100 × 63 = $18.9

The original cost of the three shirts is

63 - 18.9 = $44.1

Since the shirts are of the same price,the original cost of each shirt is

44.1/3 = $14.7

Part C

Each employee gets an additional 10% off the already discounted price. If an employee buys an item with an original price of $40, then the additional amount taken off is

10/100 × 40 = $4

The amount that the employee would pay is

40 - 4 = $36
