$2,900 you have to subtract from the $4,000 and it is $1,100 you have left
The function that models exponential growth is:
P(t) = P0*(1 + r)^t, where
P0 = P(0) is the initial value of P
r is the growth rate as a decimal
In our case we have:
P(0) = 2800
r = 0.035 or 3.5%
P(t) = 2800*(1 + 0.035)^t
P(t) = 2800*(1.035)^t
The same exponential function written using y and t is:
y = 2800*1.035^t.

If you do the calculations and have in mind the data given then we may say that 1) The company must sell 250 cameras in one day and
2) If the manufacturer increases the production by 50 then the profut would be 400.
