Answer:
$18.06
Explanation:
The price the pawn shop charged for the DVD player was 40% more than what it paid, so was ...
$12.00 + $12.00 × 0.40 = $12.00×(1 +0.40) = $16.80
__
The tax on the purchase is this price multiplied by the tax rate:
tax = 0.075×$16.80 = $1.26
__
Then the total including tax is ...
$16.80 +1.26 = $18.06 . . . . . total cost of the DVD player
