Answer provided by our tutors
let
x = the cost of one orange
y = the cost of one lemon
5x + 3y = we need to find the cost of five oranges and three lemons
Two oranges and five lemons cost $2.95:
2x + 5y = 2.95
Three oranges and two lemons cost $2.50:
3x + 2y = 2.50
by solving the system of equations:
2x + 5y = 2.95
3x + 2y = 2.50
we find:
x = $0.6
y = $0.35
click here to see the step by step solution of the system of equations:
5x + 3y = 5*0.6 + 3*0.35 = $4.05
five oranges and three lemons cost $4.05.
