9. Liz works at the ballpark selling bottled
water. She sells 37 bottles in one shift. The
large bottles sell for $5 each and the small
bottles sell for $3 each. At the end of one
game, she has taken in $131.
a) How many large bottles did Liz sell?
b) How many small bottles did she sell?

10 big and 27 small

Step-by-step explanation:

First do a random amount and move closer to the answer by changing the amount of bottles

110/5=22

3 x 7 = 21

Bottles too little so less big water bottles

50/5=10

81/3=27

37 bottles so Liz sold 10 big bottles and 27 small bottles.

72 is the answer to this problem
