A tutot earns $105 for 3 hours of tutoring. How much would she earn if she tutored for 8.5 hours?

$297.50

Step-by-step explanation:

If she earns 105 for three hours, she would be earning $35 an hour.

105/3=35

If she works 8.5 hours, to find the amount you would multiply the hourly rate ($35) by 8.5. So, the answer is

8.5x35=$297.50

297.50

Step-by-step explanation:

105$ = 3 hours

105 + 105 = 210 which is 6 hours.

105 ÷ 3 is 35$ which means each hour is 35$ earned.

210 + 35 + 35 = 280 which is 2 more hours added.

Half of 35$ is 17.50

So 280 + 17.50 = 297.50
