Question

you are having a dinner party for 15 people, and one item on the menu is avocado and grapefruit salad. Each salad calls for 1/3 of an avocado and 1/2 of a grapefruit, both peeled and seeded. How many avacodos and grapefruits will you need if the yield percent for avocados is 60% and for grapefruit is 50% ?

Expert Solution
Step 1

Let A and G represent the number of avocados and grapefruits needed.

Given that the yield percent for avocado is 60%.

It means that only 60% of the avocado is available for use in the salad,

As=0.6A

Similarly, 50% of grapefruit is available for use in the salad,

Gs=0.5G

Given that each salad requires 13rd of an avocado and 12th of a grapefruit,

13·As+12·Gs=1 salad13·0.6A+12·0.5G=1 salad0.2A+0.25G=1 salad
