Answer:
$615.63
Step-by-step explanation:
In this question, we are asked to calculate the cost of a refrigerator given the original cost, tax amount and rebate. We proceed as follows:
Firstly, we calculate the tax to be paid. This is at 8.5%.
Mathematically, tax amount = 8.5/100 * 678 = $57.63
Total amount to be paid is thus 57.63+678 = $735.63
We subtract the amount for the rebate = 735.63 - 120 = $615.63
