To find the answer first we will multiply to see how much the books cost. Then we will subtract 50 by the amount of money she has to pay. Then we will check our work to makes sure we are %100 right. Lets do it:-
Lets multiply:-
10 × 2 = 20
So, 10 books cost 20m.
Lets subtract:-
50 - 20 = 30
So she gets 30m in chage.
CHECK OUR WORK:-
30 + 20 = 50
We were RIGHT!!!
So, Coley would receive 30m (B) 30m) in change is she pays with a 50 dollar bill.

Answer:
3 1/5 hours
Step-by-step explanation:
1/4 book in 1 1/3 hours.
1 1/3 = 4/3
1/4 book in 4/3 hours
We can set up a proportion.
1/4 book is to 4/3 hours as 3/5 book is to x hours.
(1/4) / (4/3) = (3/5) / x
Cross multiply:
(1/4)x = 4/3 × 3/5
(1/4)x = 12/15
Multiply both sides by 4.
x = 48/15
Reduce:
x = 16/5
x = 15/5 + 1/5
x = 3 1/5
Answer: 3 1/5 hours
