A snack stand sells bottles of water for $1.35 each . Sam needs to buy as many bottles as he can. He can spend no more than $20. How much money will Sam have left after he buys the bottles of water?
If Sam buys 14 water bottles, he will have spent 18.9, so when you subtract 20 (the limit) from 18.9 (how much money he'll spend on the water bottles) you get 1.1
