Fred went to pick oranges at a citrus farm. He picked 5 bushels of oranges and paid $31.75. How much would it cost to pick 7 bushels of oranges?

So let’s make an equation

5-31,75$
7-x
We have to multiply 7 by 31,75 and 5 by X, but since x isn’t a number, hence we’ll put it in the beginning

X=7 x 31,75=222.25

222.25 divided by 5 =44.45

So the answer is: 44,45$
