4-12.

On a hot summer day, Leo and Stefano decided to buy some refreshments at the Fruit and Smoothies store. Fruit kabobs cost $$1.75$ each and smoothies cost $$2.50$ each.

Leo ordered two fruit kabobs and one smoothie. How much did he spend?

Hint (a)
Find the cost of the fruit kabobs.
$(2)($1.75) = $3.50$
More Help (a):
Add this to the cost of the smoothie to find the total cost.
$$3.50 + $2.50 = $6.00$
Answer (a):
The total cost was $$6.00$ .

Stefano ordered three fruit kabobs and four smoothies. How much did he spend?

Hint (b):
This is a very similar problem to part (a).
Remember, this time there is more than one smoothie.
Answer (b):
$$15.25$

Arturo could not decide, but he had $$9.00$ he could spend on fruit kabobs and smoothies. He knows he wants at least one of each. What are some combinations he can afford? (Show at least three possibilities.)
Hint (c):
Try different combinations, using the method demonstrated in part (a). Check whether the total cost is $$9.00$ or less.
