Question

Jerry charges $15 for each lawn that he cuts. Depending homework and chores, he has time to cut at most 10 lawns a week. Jerry has determine his fixed cost to be $10 a week and that his profit for a week can be modeled by the function y = 15x − 10. Which BEST describes the domain for this function?

Answer 1

Answer: 0 less than or equal to x less than or equal to 10

Explanation:

Answer 2

Explanation:

Jerry charges $15 for each lawn that he cuts. He can cut at most 10 lawns because of his limited time which is due to chores and homework. This means that if he is able to cut lawns, he would be making 10×15 = $150. This is the maximum that he can make. Also, Jerry has determined his fixed cost to be $10 a week. Therefore, his maximum profit will be

150 - 10= $140

This is modelled by the function below

y = 15x − 10

Where y(profit) depends on x(number of lawns).

The domain of this function is the set of all possible values of x for which the function is defined.

The domain of the function is ( x lesser than or equal to 10)
