Question

The tuition T for one year at a college can be approximated by the equation T=1/8x+19 where x is the year since 2000, and T is tuition in thousands of dollars. Use the equation to estimate the tuition for one year at this college in 2020.

Answer 1

$21,500

Explanation:

T=1/8x+19

since x is the year since 2000, the year 2020 would be when x=20.

Sub x=20 in the equation

T=(1/8)(20)+19

T=20/8 +19

T=19 + 5/2

T=43/2

T=21.5

Since T is tuition in thousands, multiply T=21.5 by 1000. The tuition is $21,500.
