Answer:
7 hours
Step-by-step explanation:
If you divide
171 ÷ 9
you find the $ Tammy made in 1 hour.
171 ÷ 9 = 19
So Tammy made 19 for 1 hour of work.
Then we divide 133 by 19 to find out for how many hours she has to work.
133 ÷ 19.67 = 7. So Tammy has to work 7 hours to make $133.
Hermione has 7-$5 dollar bills and 5-$1 dollar bills.
