Multiple Choice

Suppose your annual income is $I ( t ) = 60,000 + 1,800 t ( 0 \leq t \leq 3 )$ dollars per year, where t represents the number of years since you began your job, while your annual expenses are $E ( t ) = 50,000 + 1,400 t ( 0 \leq t \leq 3 )$ dollars per year. Find the area between the graphs of $I ( t )$ and $E ( t )$ for $( 0 \leq t \leq 3 )$ . Round your answer to the nearest dollar.

A) Area = $31,800
B) Area = $33,600
C) Area = $188,100
D) Area = $344,400
E) Area = $156,300
