Acompany's revenue function and cost function are as follows: r(x) = 0.55x and c(x) = 10 + 0.05x. what is the minimum number of units, x, that must be sold for the company to make money

Minimum number of units sold to make profit is equal to 20

Step-by-step explanation:

Revenue earned by the company as a function of number of units sold as x:

R(x) = 0.55x

Cost for selling units as a function of number of units sold as x:

C(x) = 10 + 0.05x

Net profit earned by the company = (Revenue earned by the company) - (Cost of selling units)

P(x) = (0.55x) - (10 + 0.05x)

P(x) = 0.55x - 10 - 0.05x

P(x) = 0.5x - 10

To earn profit the following condition should satisfy: P(x) ≥ 0

0.5x - 10 ≥ 0

0.5x ≥ 10

x ≥

x ≥ 20

step-by-step explanation:

10.50 + taxes which added up to 11.50
