Answer:
The correct answer is C. US$ 13.38
Step-by-step explanation:
1. Let's check the information given:
Cost of winter coat = US$ 237
Cost of mittens = US$ 3.15 each
Sales tax rate in New York = 5.5%
Total purchase = Cost of winter coat + Cost of mittens
Total purchase = 237 + 2 * 3.15
Total purchase = 237 + 6.30
Total purchase = US$ 243.30
2. Calculation of the Sales tax rate in New York
Sales tax rate in the purchase = 243.30 * 5.5%
Sales tax rate = 243.30 * 0.055
Sales tax rate = US$ 13.38
