Using a proportion, determine how many pounds of apples a person needs for a pie for 10 when the recipe calls for three pounds of apples for an apple pie for eight people.

Answer 1

You will need x lbs, where the ratio of lbs/people remains the same. That is,

3/8 = x/10
30 = 8x
x = 15/4 = 3 3/4 lbs

Oh, and you'll also need a larger pie pan...
