Answer:option c is the correct answer
Step-by-step explanation:
He just bought a sewing machine whose full price was $90, but he got 40% off, because the store was having a sale. This means that the amount of money that was reduced from the original price of the sewing machine would be
40/100 × 90 = 0.4 × 90/= 36
Therefore, the price of the sewing machine is 90 - 36 = 54
Kirk lives in Nebraska, which has a sales tax of 5.5%. The value of the 5.5% tax would be
5.5/100 × 54 = 0.055 × 54 = 2.97
Therefore, the total amount that Kirk paid would be
54 + 2.97 = $56.97
