Explanation:

Question 16

Step1: Add 1.72 and 7.39

$1.72 + 7.39 = 9.11$

Step2: Add the result to 6.6

$9.11 + 6.6 = 15.71$

Step1: Subtract the cents part: 54 - 37 = 17 (cents)

Step2: Subtract the dollars part: 88 - 77 = 11 (dollars)

Step3: Combine the results: $88.54 - 77.37 = 11.17$

Step1: Subtract the reduction from the original price

$15.83 - 4.45 = 11.38$

Answer:

15.71
