Sales: Income I from product given by I(t)=24000-22000e^...

The monthly income I, in dollars, from a new product is given by: I(t)=24,000-22,000e^-0.005t, where t is the time, in months, since the product was first put on the market.

a. what is the monthly income after the 10th month and after the 100th month?

b. what will the monthly income from the product approach as the time increases without bond?

i need help setting this problem up...help asap. thanks!

I'm not seeing what there is to "set up"...?

a) They gave you the equation for the income I after t months, and asked for the values at t = 10 and t = 100. Plug-n-chug.

b) Use what you know about exponentials, particularly those with negative exponents, to determine the value as t gets very large. The graph might help.
