Jack bought 3 slices of cheese pizza and 4 slices of mushroom pizza for a total cost of \$12.50. Grace bought 3 slices of cheese pizza and 2 slices of mushroom pizza for a total cost of \$8.50. What is the cost of 1 slice of mushroom pizza?

• Math -

Let x = slices of cheese pizza and y = mushroom.

3x + 4y = 12.5
3x + 2y = 8.5

Subtract second equation from first.

2y = 4
y = 2

I hope this helps. Thanks for asking.
