Stella earned $72 working 9 hours. How much will she earn in 23 hours?

Stella would earn $184 in 23 hours.

Step-by-step explanation: First we need to find the unit rate so start by dividing by 9

Now we know every hour Stella will earn $8. We can now multiply the amount for 1 hour by 23 to get the amount for 23 hours.

8x23=184

1*23=23

Now we can see that Stella would earn $184 for working 23 hours.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
