Answer:
$36 (option a)
Explanation:
the original price of the headphones is $80. now, we can apply the 40% discount:
$80 × (100% - 40%)
= $80 × 60%
= $80 ÷ 100 × 60
= $48
the coupon and rebate will help to shave off another $8 + $4 = $12.
thus, the final cost of the headphones would be:
$48 - $12 = $36 (option a)
i hope this helps! :D
