Problema Solution
The Fussy food shop makes a gourmet low-fat blend of pretzels and potato chips. If the cost of pretzels is $2.40 per pound and the cost of potato chips is $3.40 per pound, how many pounds of pretzels and how many pounds of potato chips should be used to make a 2 pound blend that costs $3.00 per pound?
Answer provided by our tutors
let
x = lbs of pretzels
y = lbs of potato chips
we need to make 2 lbs blend that will cost $3.00 per pound thus
x + y = 2
2.40x + 3.40y = 3*2
by solving the system of equations we find
x = 0.8 lbs
y = 1.2 lbs
