Answer 2

Answer:

1. 15t + 30 ≥ 90

2. t ≥ 4

3. 4, 4.5, 5

Step-by-step explanation:

1.

She starts by charging a fixed fee of $30.

cost = ... + 30

She charges $15 per hour. For t hours, she charges 15t.

total charge = 15t + 30

She needs to make at least $90. That means the amount she makes has to be equal to or greater than $90.

15t + 30 ≥ 90

2.

15t + 30 ≥ 90

15t ≥ 60

t ≥ 4

She needs to work at least 4 hours.

3.

All values that are 4 or greater work: 4, 4.5, 5
