Answer 2

Answer:

The correct answer is 9x + 7 y $\geq$ 147 where Ashley works for x hours as lawn mower and y hours as babysitter per week.

Step-by-step explanation:

Ashley works in two different jobs namely mowing lawns and babysitting.

Let Ashley mow lawn for x hours and babysit for y hours in a week.

Ashley's earning for every hour she mow is $ 9. Total earning mowing lawn is $ 9x.

Ashley earns $7 for every hour she babysit. Total earning babysitting is $ 7y.

Total earning per week $ (9x + 7y).

Ashley's earning per week is at least $147.

∴ The required inequality to describe the above case is 9x + 7 y $\geq$ 147.
