Answer:
The correct answer is 9x + 7 y [tex]\geq[/tex] 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 [tex]\geq[/tex] 147.
