a. $442.36

b. $442.37

c. $13.38

d. $13.39

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
