Given is :

Let the total number of sparkling cans of water used in a day be =x

As mentioned, the family uses more than 15 cans each day so inequality becomes ,
x>15

As they buy cases of water with 24 cans in each case. So less than 1 case is used in a day.

Number of cans used in a day is more than 15, so approx number of cans used in 30 days will be =
30*15=450

As each case contains 24 cans, so the number of cases that will contain 450 cans will be,
(450)/(24)=18.75 cases. Rounding this off to nearest whole number, we get 19 cases.

Hence, the family buys around 19 cases of sparkling water in 30 days.
