A frozen dinner at a grocery store is purchased for $2.20 wholesale and is marked up by 40 percent. A customer wants to buy four frozen dinners. How much will the customer pay, including paying 9 percent sales tax? Round your answer to the nearest cent. $8.80 $10.07 $13.43 $14.39

$13.43

Step-by-step explanation:

Given that :

Price of dinner wholesale = $2.20

Markup % = 40%

Hence, selling price = (100 + 40)% * $2.20

Selling price = 140% * $2.20

Selling price = 1.4 * $2. 20 = $3. 08

Hence, price of 4 frozen dinner :

$3. 08 * 4 = $12.32

9% sales tax:

9% * $12.32

0.09 * $12.32 = 1.1088

Total amount paid :

$(12.32 +. 1.1088)

= $13.4288

= $13.43

what i would say the best answer is a. 40.5
