(Simplify your answer. Do not include the S symbol in your answer.)Explanation / Answer
The formula given,
T(x) = 26x2+828x+15,588
year ending 2010 means, 10 years after 2000
i.e x = 10
subtituting the value of x in the function, we get the tuition and fees for the school year ending 2010
T(10) = 26(10)2+828(10)+15,588
T(10) = 2600+8280+15588
T(10) = $26468
the tuition and fees for the school year ending 2010 = $26468
