Question 903223: It Algebra College
A recycling company can recycle used paper into mulch and paper. In given day, the company turns out a total of 359 units of mulch and paper and make profit of $23 on unit of mulch and $5 on a unit of paper. How many of each unit must be produce and sold in order to make a profit of $5,215? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! m+p=359,
23*m+5*p=5215
m=359-p
23*(359-p)+5*p=5215
8257-23p+5*p=5215
-18*p=-3042
p=169
m=359-p
m=190 at $23 and p=169 at $5
check
190+169=359
23*m+5*p=5215
23*190+5*169=5215
4370+845=5215
5215=5215
ok
