Asked by Me

Bob is making sandwiches for a school picnic. He is making these types: ham, cheese, and turkey. So far, he has made 12 ham sandwiches, 20 turkey, and 4 cheese. What combination can he make so that exactly 1/5 of the sandwiches are cheese?
Answered by Steve
If he makes x more cheese sandwiches, then

(12+20+4+x) = 5(4+x)
x = 4

check: 4+4=8 cheese out of 40 total.

You can try other settings as well.
