Alan repairs televisions. his revenue is modeled by the function r(h)=10+30h for every h hours he spends repairing televisions. his overhead cost is modeled by the function c(h)=5h2−25 dollars.

after how many hours does he break even?

After 7 hours, he breaks even.

Step-by-step explanation:

Break Even Point is when Revenue = Cost.

So we equate the revenue function and cost function, and figure out the value of to find his break even hours.

The number of hours, h, cannot be negative, so h = 7 is the right answer.
