After selling 25 tootsie rolls and 15 lollipop I made $10. After selling 10 tootsie rolls and 15 lollipops I made $8.50. How much was charged for each tootsie roll and each lollipop?

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
