Answer
Let the cost of one apple be x
Let the cost of one orange be y
System of equations is
10x + 15y = 20
5x + 6y = 8.5
Cost of apple = $0.5
Cost of orange = $1
Step-by-step explanation
Let the cost of one apple be x
Let the cost of one orange be y
10 apples and 15 oranges cost $20.
10x + 15y = 20
5 apples and 6 oranges cost $8.50
5x + 6y = 8.5
We can now write the two equations together
10x + 15y = 20
5x + 6y = 8.5
Solving this system of equations,
x = 0.5
y = 1
