Question

Kate is buying 12-packs of bottled water. She has storage space for 65 bottles. She plans to take 11 of them with her on a camping trip this weekend, and will store the rest. What is the greatest number of 12-packs she should buy? Explain how to solve the problem using an inequality.

Answer 1

if Kate has 65 bottles to store, you would just add up 12 continuously till you reach 65 or go below 65, so 12+12=24 24+12=36 36+12= 48 48+12 = 68 so therefore she'd need to store atleast 48 bottles of water.


(hope this helps!)

Answer 2

Explanation:

sample response : Let the variable x be the number of packs purchased, and 12x = total number of water bottles. Since 11 are removed, 12x - 11 is the total she needs to store. So, 12x - 11 must be less than or equal to 65. Solving this, you get x is less than or equal to 6 1/3. This means Kate should buy a maximum of 6 12-packs, since she cannot buy part of a 12-pack.
