While on vacation Craig bought a pair of sunglasses for $15.98 for $7.99 5 postcards and a beach towel the beach towel cost 0.50
NISA [10]

Answer:

$0.79.

Step-by-step explanation:

Let T= The price of beach towel,

P = The cost of each postcard.

S = The cost of sunglasses.

H = The cost of hat.

We have been given that while on vacation Craig bought a pair of sunglasses for $15.98. The beach towel cost 0.50 cents more than half the price of sunglasses.

We can set this information in an equation as:

T=\frac{15.98}{2}+0.50

T=7.99+0.50  

T=8.49  

We are told that Craig gave the cashier $40 and got 3.59 change and each postcard cost the same. So we can set this information in an equation as:

T+5P+S+H=40-3.59

Let us substitute our given values.

8.49+5P+15.98+7.99=40-3.59  

Let us combine like terms.    

32.46+5P=36.41      

Let us subtract 32.46 from both sides of our equation.

32.46-32.46+5P=36.41-32.46

5P=3.95  

Let us divide both sides of our equation by 5.

\frac{5P}{5}=\frac{3.95}{5}  

P=0.79  

Therefore, each postcard costs $0.79.
