Question

5. Miguel has an after-school job. He works

between 15 and 25 hours each week and is paid
$12 per hour. What is an appropriate domain for
this scenario?
A. All real numbers such that 15 B. All real numbers such that 180 < x < 300
C. All real numbers
D. All real numbers such that x>0

Answer 1

The domain is 15 ≤ x ≤ 25

Explanation:

The given parameters are;

The number of hours Miguel works each week = Between 15 and 25 hours

The amount he is paid per hour = $12

Therefore, we have;

The domain is all real numbers, 'x', such that 15 ≤ x ≤ 25

The amount Miguel makes each week, 'y' is between; 12 × 15 ≤ A ≤ 12 × 25

Therefore the range is 180 ≤ y ≤ 300.
