Question

Kendra is buying bottled water for a class trip. She has 16 bottles left over from the last trip. She buys bottles by the case to get a good price. Each case holds 24 bottles. How many cases will she have to buy if she wants to have a total of 160 bottles of water?

Answer 1

160-16 gives you 144 , so i divided 144 by 24 and got 6, she had 16 bottles left over so 144+16 = 160. she will need to buy 6 cases of water

Answer 2

Answer=6

Given the information, the following equation can be made, where x is equal to the number of cases she needs to buy.

160=16+24x
subtract 16 from both sides
144=24x
divide both sides by 24
6=x

She will have to buy 6 cases to have a total of 160 water bottles.
