4. Mrs. Kreger created the expression
Charra [1.4K]

Here, we are required to find how many hours per week does Lindsey need to study if she wants to have an average of at least 90

Lindsey needs to study for at least 15.25 hours to have an average of 90

Given expression:

4(h + 11) – 15

Where,

h = number of hours

For Lindsay to have at least 90

4(h + 11) – 15 = 90

open parenthesis

4h + 44 - 15 = 90

4h + 29 = 90

4h = 90 - 29

4h = 61

Divide both sides by 4

h = 61/4

h = 15.25 hours

Therefore,

Lindsey needs to study for at least 15.25 hours to have an average of 90
