The average American consumes about 20 gallons of ice cream in one year. At this rate, how many liters of ice cream will 50 Americans consume in one week? Round to the nearest hundredth.

1 year has around 52.1429 weeks

We are given that one American consumes around 20 gallons of ice cream in a year. This means that the consumption is 20 gallons in 52.1429 weeks.

Now, first we will calculate the amount consumed by 1 American in one week using cross multiplication as follows:

consumption per week = (1*20) / (52.1429) = 0.38356 gallons

Now, to know the consumption of 50 Americans in one week, we will simply multiply the consumption of one American by 50 as follows:

consumption of 50 Americans = 0.38356 * 50 = 19.18 gallons/week
