Please answer the following question by reasoning step-by-step.
Charlotte is making a pie. She can't decide if she will make cherry or blueberry. So she decides to make whichever pie is cheapest. Both pies will need $2 for flour, $1 for sugar and $1.5 for eggs and butter to make the crust. The blueberry pie needs 3 pounds of blueberries. The blueberries come in 8 oz containers for $2.25. For the cherry pie, she needs 4 pounds and they come in a four-pound bag for $14. What is the total price to make the cheapest pie?

18
The crust will cost $4.

5 because 2 + 1 + 1.

5 = 4.

5.

She will need 6 containers for blueberries because 3 x (8 / 16) = 6.

The blueberries will cost $13.

5 because 6 x 2.

25 = 13.

5.

The blueberries are cheaper because 13.

5 < 14.

The blueberry pie will cost $18 to make because 4.

5 + 13.

5 = 18.

.

So, the final answer is 18
