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? A) number of yards Jerry cuts; x ≥ 0 B) number of yards Jerry cuts; x ≤ 10 C) number of yards Jerry cuts; x ≥ 10 D) number of yards Jerry cuts; 0 ≤ x ≤ 10

Answer 1

d

Explanation:

Answer 2

Answer: D) Number of yards Jerry cuts; 0 ≤ x ≤ 10

Explanation:

Here the given function that describes the total profit,

y = 15 x - 10

Where x represents the number of lawns Jerry cut in a week.

But, Depending homework and chores, he has time to cut at most 10 lawns a week.

Thus, x ≤ 10

Also, the number of lawns can not be negative.

Therefore, x ≥ 0

And, the value of x will decide the domain of the function y,

Thus, the domain of the given function is,

0 ≤ x ≤ 10

⇒ Option D is correct.
