The bar graph shows the average dormitory charges at public and private four-year U.S. colleges. Use the information displayed by the graph to solve Exercises 65-66. a. Use the numbers shown by the bar graph to find the total dormitory charges at public colleges for a four-year, period from the school year ending in 2010 through the school year ending in 2013. b. The model a n = 225 n + 4357 describes dormitory charges at public colleges in academic yearn, where n = 1 corresponds to the school year ending in 2010, n = 2 to the school year ending in 2011, and so on. Use this model and the formula for S n to find the total dormitory charges at public colleges for a four-year period from the school year ending in 2010 through the school year ending in 2013. Does this underestimate or overestimate the actual sum that you obtained in part (a)? By how much?

Solution Summary: The author explains how to calculate the total dormitory charges at public colleges over the period of four years from 2010 to 2013.
The bar graph shows the average dormitory charges at public and private four-year U.S. colleges. Use the information displayed by the graph to solve Exercises 65-66.
a. Use the numbers shown by the bar graph to find the total dormitory charges at public colleges for a four-year, period from the school year ending in 2010 through the school year ending in 2013.
b. The model
a
n
=
225
n
+
4357
describes dormitory charges at public colleges in academic yearn, where
n
=
1
corresponds to the school year ending in 2010,
n
=
2
to the school year ending in 2011, and so on. Use this model and the formula for
S
n
to find the total dormitory charges at public colleges for a four-year period from the school year ending in 2010 through the school year ending in 2013. Does this underestimate or overestimate the actual sum that you obtained in part (a)? By how much?
