Answer:
17.1 hrs
Step-by-step explanation:
If she tutored 2 1/3hours the first week and 1.5 hours the second week .
That’s 2 1/3 hrs + 1.5hrs
Change 2 1/3 to improper fraction. It becomes
7/5 = 1.4 hrs
1.4 hrs + 1.5 hrs = 2.9 hrs
So she’s tutored 2.9 hrs in the first 2 weeks
Hours remaining for her to tutor this week = hours she tutors every month - hours already done this month
That’s 20 hrs - 2.9 hrs
= 17.1 hrs
She has 17.1 hours more to tutor this month
