Lily is in charge of bringing bottled water to a party that has 37 guests. Bottled water is sold in packs of 36 and each pack costs $42.12.

Part A: enter the total number of packs of water Lily will need to bring to the party if each guest is to have 3 bottles of

water.

Part B: enter the total cost, in dollars, Lily will spend on bottled water for the party.

A) 4 packs

B) $168.48

Step-by-step explanation:

A) Lily will need to bring 4 packs of bottled water because 3 bottles per guest is 37 times 3, which gives us 111 water bottles. If each pack has 36, divide 111 water bottles by 36 giving us 3.08333333333 packs. Since you cannot buy 3.08333333333 packs of bottled water, Lily will need to round up to the nearest whole number to insure that each guest has exactly 3 water bottles. When you round up it will be 4 packs of bottled water.

B) Because Lily is bringing 4 packs of bottled water to the party and each pack costs $42.12, multiply 42.12 by 4 to get $168.48 as the total cost of her purchase.

4 and 5)16.97 or 12√2
