77. the yearly cost of tuition (in-state) and required fees for
attending a public two-year college full time can be esti-
mated by the linear function f(x) = 64x + 2083, where x
is the number of years after 2000 and f(x) is the total cost.
(source: the college board)
a. use this function to approximate the yearly cost of
attending a two-year college in the year 2016. (hint: find
f(16).]
b. use the given function to predict in what year the yearly
cost of tuition and required fees will exceed $3200. [hint:
let f(x) = 3200, solve for x, then round your solution
up to the next whole year.]
c. use this function to approximate the yearly cost of
attending a two-year college in the present year. if you
attend a two-year college, is this amount greater than or
less than the amount that is currently charged by the col-
lege you attend?
