Answer :
The equations of E and R are illustrations of cost and revenue functions
The equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p
How to determine the break even point
The cost and the revenue functions are given as:
E = -20,000p + 90,000
R = -2,170p^2 + 87,000p
At the break even point, we have:
E = R
Substitute known values
-20,000p + 90,000 = -2,170p^2 + 87,000p
Hence, the equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p
