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 the price of the sunglasses. Craig gave the cashier $40 and got $3.59 in change. Each postcard cost the same. How much did each postcard cost?

s = sunglass

h = hat
p = postcard
b = beach towel
------------------
s = 15.98
h = 7.99
b = .50 + (1/2)s = 8.49
----------------------------
cost
15.98 + 7.99 + 8.49 + 5 p = 40-3.59

32.46 + 5 p = 36.41

5 p = 3.95

p =0.79 or 79 cents each

Hey I did one of them; now you try.

I'm clueless when it comes to this...trying to help out my 10 year old who's not feeling well =(

Me is confused

Sad

hey good job

To find out how much each postcard cost, let's first calculate the total cost of everything except the postcards and the beach towel.

The cost of the sunglasses is $15.98.
The cost of the hat is $7.99.
Therefore, the total cost of the sunglasses and the hat is $15.98 + $7.99 = $23.97.

Now, let's find the cost of the beach towel. It is given that the beach towel cost $0.50 more than half the price of the sunglasses. Half the price of the sunglasses is $15.98 / 2 = $7.99. Adding $0.50 to this, we get $7.99 + $0.50 = $8.49. So, the beach towel cost $8.49.

Next, let's calculate the total cost of the sunglasses, hat, and beach towel. This is $23.97 + $8.49 = $32.46.

Now, we know that Craig gave the cashier $40 and got $3.59 in change. Therefore, the cost of everything he bought, including the postcards, is $40 - $3.59 = $36.41.

Since we have the total cost of everything except the postcards, we can subtract this from the total cost of everything to find the cost of the postcards.

$36.41 - $32.46 = $3.95.

Since there are 5 postcards, we can divide the total cost of the postcards by the number of postcards to find the cost of each postcard.

$3.95 / 5 = $0.79.

Therefore, each postcard cost $0.79.
