Answer:
$6,000
Step-by-step explanation:
The mean value of a sample is assumed to be the same as the mean of the population. The mean of a uniformly distributed variable between 0 and 160 is:

If the mean cost for each machine is $80, the mean aggregate cost for a sample of 75 machines is:

The mean aggregate maintenance cost is $6,000.
So you would do 41.7g - 20.2g and get 21.5g, then multiply it by 140g. 140g x 21.5g = 3010g
210000 * .20 = 42000 down payment
210000 * .04 = 8400 closing costs
197040.76 + 42000 + 8400 = 247440.76 total cost
