Question

If a party planner assumes 2 bottles of sparkling water per 5 guests, how many bottles must she purchased for a party of 68?

Answer 1

To supply a party of 68 guests with sparkling water based on the ratio of 2 bottles for every 5 guests, the party planner needs to purchase 28 bottles.

Step-by-step explanation:

To determine how many bottles of sparkling water are needed for a party of 68 guests, we use a ratio based on the assumption that 2 bottles are needed for every 5 guests. This can be calculated as follows:

1. Determine the ratio of guests to bottles, which is 5 guests to 2 bottles.
2. Divide the total number of guests by the number of guests included in the ratio. In this case, 68 ÷ 5 = 13.6, which means you would need 13.6 times the number of bottles in the ratio for all guests.
3. Since you can't purchase a fraction of a bottle, round up to the nearest whole number. Therefore, 13.6 rounds up to 14.
4. Multiply the rounded number by the number of bottles per ratio. So, 14 × 2 = 28.

Therefore, the party planner must purchase 28 bottles of sparkling water to ensure each guest can have their share according to the given ratio.
