Answer :a. $80.07

Price of graphing calculator = $83

Discount percentage = 15%= 0.15

Discount amount = 83 * 0.15 = 12.45

Price of calculator after discount = price - discount amount

= 83 - 12.45 = 70.55

Enzel pays 4.5% sales tax on the discounted price pays a shipping fee of $6.35.

Sales tax percentage = 4.5%= 0.045

Sales tax amount = 70.55 * 0.045 = 3.17475

Now Online price = Discounted price + sales tax amount + shipping fee

= 70.55 + 3.17474 + 6.35 = 80.07

$80.07 is the total of Enzel’s online purchase
