Problema Solution
If an orange cost twice as much as an apple and an orange plus an apple is equal to .72, how much does one apple cost
Answer provided by our tutors
let
x = the cost of one orange
y = the cost of one apple
an orange cost twice as much as an apple
x = 2y
an orange plus an apple is equal to .72
x + y = 0.72
by solving the system of equations
x = 2y
x + y = 0.72
we find
x = $0.48
y = $0.24
