A fast food restaurant has a cost of production of c(x) = 12x + 120 and revenue of R(x) = 6x. When does the company start to turn a profit? x = ?
Added by Jennifer J.
Step 1
This happens when the revenue (R) is greater than the cost of production (c). So, we need to find the value of x for which R(x) > c(x). This means we need to solve the inequality 6x > 12x + 120. Subtract 12x from both sides to get -6x > 120. Then, divide Show more…

A fast-food restaurant has a cost of production C(x) = 12x + 147 and a revenue function R(x) = 5x. When does the company start to turn a profit?

The cost function for a certain company is $C=60 x+300$ and the revenue is given by $R=100 x-0.5 x^{2} .$ Recall that profit is revenue minus cost. Set up a quadratic equation and find two values of $x$ (production level) that will create a profit of $\$ 300$ .
