While on vacation, craig bought a pair of sunglasses for $15.98, a hat for $7.99, 5 postcards, and a beach towel. the beach towel cost $0.50 more than half of the price of the sunglasses. craig gave the cashier $40.00 and got $3.59 in change. each postcard cost the same, how much did each postcard cost?

Each postcard cost $0.79

Step-by-step explanation:

Craig bought various items at a particular price let us represent the items as follows:

pair of sunglasses = $15.98

Hat = $7.99

Let the price of each postcard = a

Total price of 5 postcards =$5a

Beach towel = 0.50 + 1/2 ×  15.98 = $8.49

He gave the cashier $40 and got a change of $3.59. That means he paid 40-3.59 = $36.41  for the whole goods he bought.

Total amount of goods bought can be computed as

15.98 + 7.99 + 5a + 8.49  = 36.41

32.46  + 5a = 36.41

5a = 36.41 - 32.46

5a = 3.95

divide both side by 5

a = 3.95/5

a = 0.79

Each postcard cost $0.79

-2 is the right

3 is greater then both of those numbers
