Question

Luis wants to buy a skateboard that usually sells for $79.87. All merchandise is discounted by 12%. What is the total cost of the skateboard if Luis has to pay a state sales tax of 7.25%

Answer 1

$75.38

Explanation:

12 : 100 = x : 79.87

x = 79.87 * 12 / 100

x = 0.7987 * 12

x = 9.5844 = discount

Price = 79.87 - 9.5844 = $ 70.2856

7.25 : 100 = x : 70.2856

x = 70.2856 * 7.25 / 100

x = 70.2856 * 0.0725 = 5.095706 = taxes

final price = 5.095706 + 70.2856 = 75.381306
