The first thing we are going to do for this case is define variables:
 x: gallons of paint
 y: brushes
 We then have the following expression:
 f (x, y) = 13x + 9y
 For x = 1 and y = 2 we have:
 f (1, 2) = 13 (1) + 9 (2)
 f (1, 2) = 13 + 18
 f (1, 2) = 31
 Answer:
 The total cost, not including tax, of the brushes and the paint they bought is:
 $ 31

A company'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
Oduvanchick [21]

Answer:

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

<em>Net profit earned by the company = (Revenue earned by the company) - (Cost of selling units)</em>

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 ≥ \frac{10}{0.5}

x ≥ 20
