Let the apple equal to x and let the banana equal to y
Equation one is x+y= 1
Equation two is 3x+2y= 2.40
Because we are doing the elimination method, multiply all of equation one by 3
3x+3y=3
3x+2y=2.40
(subtract the equations from one another)
So now you have y=60 cents
So, one banana costs 60 cents
