Suppose your daily revenue from selling used DVDs is

R(t) = 100 + 10t (0 t 5)

dollars per day, where t represents days from the beginning of the week, while your daily costs are

C(t) = 76 + 5t (0 t 5)

dollars per day. Find the area between the graphs of R(t) and C(t) for 0 t 5. $

What does your answer represent?

-average revenue per day

-average cost per day

-average profit per day

-total revenue for the week

-total cost for the week
