Using proportions, it is found that the estimate of the the per capita consumption from 2011 was of 29.25 gallons.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The amount in 2012 was a increase of 5.3% from 2011, that is, 105.3% = 1.053 of x, and the consumption per capita was of 30.8 gallons, hence:
1.053x = 30.8
x = 30.8/1.053
x = 29.25 gallons.

Hi this not a answer but this can help you use photo math
Answer:
$455
Step-by-step explanation:
The computation of the principal is shown below:
As we know that
Amount = Simple interest + Principal
Let us assume the principal be X
So,
Amount = $500
Simple interest = Principal × rate of interest × time period
= X × 5% × 2 years
= X × 0.1
So, the principal is
$500 = X × 0.1 + X
$500 = 1.1 × X
So, the X is $455 i.e principal
