Answer:
Selling price of a shoes= $ 29.99
a) The sales tax on shoes= 6.5%
Total cost of shoes= $ 29.99 + 6.5% of 29.99
Total cost of shoes= $ 29.99 + [tex]\frac{6.5}{100}[/tex] × 29.99
Total cost of shoes= $ 29.99+ 1.95
Total cost of shoes= $ 31.94
b) Cost of shipping = 15 % of total cost
cost of shipping = [tex]\frac{15}{100}[/tex] × 31.94
Cost of Shipping= $ 1.47
Total Cost of shoes plus shipping= $ 31.94 + 1.47
Total cost of shoes= $ 36.41
Since total cost is greater than $ 35 we are qualified for the discount of 10% on original price of shoes
Now, price of shoes= $29.99 - 10 % of 29.99
Price of shoes= $ 27
The New cost of shoes after discount =$ 27+ $ 1.47
New cost of shoes= $28.47
