Answer:
$7.89
Step-by-step explanation:
Given that Miguel spends $12.88 on 2 comic books then the amount spent on 1 book given that the prices of the books are equal will be
= $12.88/2
= $6.44
Given that the store reduced the price of each comic book by $1.45 then the price P of 1 comic book before the sale
P = $6.44 + $1.45
= $7.89
The cost of 1 comic book before the sale ( which is before the reduction in price) is $7.89
