Problema Solution
a grocer has two kinds of candies. One costs $5/kg and another costs $4.20/kg. How many kilograms of each type of candy should be mixed in order to get 60 kg of a mixture worth $4.80/kg?
Answer provided by our tutors
let
x = kg of the $5/kg type of candy
y = kg of the $4.20/kg type of candy
the mix weights 60 kg and it costs $4.80/kg
x + y = 60
5x + 4.20y = 4.80*60
by solving the above system of equations we find
x = 45 kg
y = 15 kg
