Bottled water is sold in packs of 18 and each pack costs $16.92.
Part A: enter the total number of packs of water Ava will need to bring to the party if each guest is to have 1 bottle of water.
Part B: enter the total cost, in dollars, Ava will spend on bottled water for the party.

Answer 1

a - about 3 packs cause you have to round up

b - $50.76

Explanation:

First you divide 42 and 18.

42/18=2.33

You have to round up cause you can't have half of a pack, you can't just buy half of a pack.

So, it is rounded to 3 packs.

Next you have to multiply the number of packs and the cost of each pack of water bottles.

16.92*3=$50.76

a - you have to buy 3 packs

b - the total cost is $50.76
