Please select the best answer from the choices provided

D, C, B, A

Step-by-step explanation:

Given the prices below:

Store A: price $99.99 and discount of 15%

15% discount :

Discounted price : (1 - 0.15) * $99.99 = $84.99

Store B: price $95.99 and discount of 12%

12% discount :

Discounted price : (1 - 0.12) * $95.99 = $84.47

Store C: price $90.99 and discount of 10%

10% discount :

Discounted price : (1 - 0.10) * $90.99 = $81.89

Store D: price $89.99 and successive discounts of 5% and 5%

5% discount :

Discounted price : (1 - 0.05) * $89.99 = $85.4905

5% discount :

(1 - 0.05) * $85.4905 = $81.22

Cheapest = store D, then then C, then B, then A

D, C, B, A

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
