Answer:
28 hours
Step-by-step explanation:
Let the number of hours required to:
Tutor = x
Walk the dog = y
If you are scheduled to tutor for 10 hours during the week
x = 10........ Equation 1
You can earn money by tutoring for $8 per hour and by walking dogs for $7.50 per hour. Create and solve an inequality that represents the number of hours you can walk dogs during the week in order to earn at least $290 for the week
$8 × x + $7.50 × y ≥ $290
8x + 7.50y ≥ 290..... Equation 2
We substitute 10 for x in Equation 2
8(10 ) + 7.50y ≥ 290
80 +7.50y ≥ 290
7.50y ≥ 290 - 80
7.50y ≥ 210
y ≥ 210/7.50
y ≥ 28 hours
The number of hours you can walk dogs during the week in order to earn at least $290 for the week is 28 hours
