Problema Solution
A supermarket is selling two types of candy, orange slices and strawberry leaves. The orange slices cost $1.29 per pound and the strawberry leaves cost $1.79 per pound. How many pounds of each should be mixed to get a 12 pound mixture that sells for $17.48? Find the number of pounds of orange slices that are required.
Answer provided by our tutors
let
o = pounds of orange slices needed for the mix
s = pound of strawberry leaves needed for the mix
the mix we need to make is 12 pounds thus
o + s = 12
the 12 pounds mix will sell for $17.48
1.29*o + 1.79*s = 17.48
by solving the system of equations
o + s = 12
1.29*o + 1.79*s = 17.48
we find
o = 8 lbs
