There are two types of coffee beans being used to make a blend of coffee. If Bean A costs $0.80 per kilogram and Bean B costs $0.45. What weight of Bean A and Bean B should be used in 10 kg of the blend to make the overall cost of the blend equal to $0.60 per kilogram?
Answer provided by our tutors
let
a = the weight of Bean A coffee
b = the weight of Bean B coffee
a + b = 10
0.80a + 0.45b = 0.60*10
by solving the above system of equations we find:
a = 4.29 kg
b = 5.71 kg
