Did you try to solve it yourself?

anonymous · Answer

yes can you tell me

pfenn1 · Answer

If you subtract the two equations from one another you get$$y - y = -0.04 x ^{2} + 8.3x -1.12x.-1.6$$$$0 = 0.04x^2-7.18x +1.6$$

I would then plug in the different possible answers and  see which one works.
