Question

The following excerpt comes from the international bottled water association:

Answer 1

Using proportions, the estimate of the per capita consumption from 2011 was 29.25 gallons.

What is a proportion?

A proportion is a fraction of the total amount, the measures are related using a rule of three.

The amount in 2012 was an increase of 5.3% from 2011,

105.3% = 1.053 of x,

The consumption per capita was 30.8 gallons,

hence:

1.053x = 30.8

x = 30.8/1.053

x = 29.25 gallons.
