Accepted Solution

A:

The cost of one slice of mushroom pizza is $2.00 dollars. This is solved by subtracting the equations:

X = cheese pizza

Y = mushroom pizza

(3X + 4Y = 12.50)

- (3X + 2Y = 8.50)

______________

2Y = 4.00

Y=2 or a slice of mushroom pizza is $2.00.

X = cheese pizza

Y = mushroom pizza

(3X + 4Y = 12.50)

- (3X + 2Y = 8.50)

______________

2Y = 4.00

Y=2 or a slice of mushroom pizza is $2.00.
