Answer:
Step-by-step explanation:
Let x = number of hours to pull weed in a day
Let y = number of hours to now lawn in a day
It takes her an average of 3 hours to pull weeds and an average of 2.5 hours to mow the lawn. She can work no more than 8 hours a day.
This means
3x + 2.5y is lesser than/ equal to 8
She charges $50 to weed and $65 to mow the lawn.
This means she charges
50x +65y
She needs to cover her expenses of $120 to make a profit. This means she needs to earn an amount greater than or equal to $120
50x + 65y greater than or equal to 120
