Answer:
Sales tax = $0.84
Total cost = $21.07
Explanations:
Cost Price = $20.99
Tax rate = 4% = 4/100 = 0.04
Sales tax = (Tax rate) x (cost Price)
Sales tax = 0.04 x 20.99
Sales tax = $0.8396
Sales tax = $0.84 (to the nearest cent)
Total cost = Cost price + sales tax
Total cost = $20.99 + $0.84
Total cost = $21.074
Total cost = $21.07 (to the nearest cent)
