Explanation:
The utility for consuming the first donut is 9 utils.
The utility for consuming the second donut is the difference from the total utility for the first two and just the first donut.
The utility for consuming the third donut is the difference from the total utility for the first three and just the first two donuts.
The utility for consuming the fourth donut is the difference from the total utility for the first four and just the first three donuts.
Since the utility for the 4th donut is less than the utility for the 3rd donut, utility begins to diminish after consuming the third donut.

Let the function of the revenue earned is given as
Here
- a and b are the limits of integral which are 0 and 1 respectively
- r is the rate of interest which is 5% or 0.05

So the present value of revenue in the first year is $61,085.92.
b-
The time in which the machine pays for itself is given as
The present value is set equal to the value of machine which is given as
$160,000 so the equation becomes:
So the total time it would take to pay for its price is 2.44 years of 29.33 months.
