$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:

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:

Let us substitute our given values.

Let us combine like terms.    

Let us subtract 32.46 from both sides of our equation.

Let us divide both sides of our equation by 5.

Therefore, each postcard costs $0.79.

f(x)=2/3x-8, which give g(x) the greatest value.
