Math Problem Statement
Find the break-even point(s) for the revenue and cost functions below. Separate multiple answers with a comma.
R(x)=125.40x−2x2C(x)=13x+1489.44
Solution
To find the break-even point(s), we need to set the revenue function equal to the cost function and solve for .
Given:
Setting :
Rearrange to form a standard quadratic equation:
Dividing through by for simplicity:
Now, we solve this quadratic equation using the quadratic formula:
Calculating the two possible values for :
So, the break-even points are approximately:
