Math multiple choice helppppppp

Answer 1

Answer: choice A. 100x - 2x^2

=====================================================

Work Shown:

R(x) = revenue = amount of money coming in

R(x) = (number of units solid)*(price per unit)

R(x) = ( x )*( P(x) )

R(x) = x*(100 - 2x)

R(x) = 100x - 2x^2

Since the price function is defined on the interval
`1 \le \text{x} \le 30`, this means the revenue is also based on this interval as well. The lowest x can be is 1, the highest is 30.
