They are identical ratios.
For questions like this, we will work backward to arrive at the initial number.
Start with the final answer. The answer is 4.5.
[divided by 3,] so we will multiply by 3
4.5 x 3 = 13.5
[Add 6], so we will subtract 6
13.5 - 6 = 7.5
[divided by 2], so we will multiply by 2
7.5 x 2 = 15

The answer is skewed in the right direction
Based on the formula given for the model of the average cost of tuition and fees, the average cost of tuition in 2010 was $25,858.
<h3>What was the average cost of tuition at private colleges in 2010?</h3>
The base year is 2000 and x denotes the number of years after 2000.
The value of x for 2010 is therefore:
= 2010 - 2000
= 10 years
The average cost of tuition in 2010 is therefore:
= 26 (10)² + 814(10) + 15,118
= 2,600 + 8,140 + 15,118
= $25,858
