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
