When 'x' units are sold, the price of each unit (p in $) is given by
p+=+2%5E%28-x%29+%2B+75
or p+=+1%2F2%5Ex+%2B+75

So when 2 units are sold, unit price i.e. price of each unit is $p+=+1%2F2%5E2+%2B+75 = $75.25.

So when 7 units are sold, unit price i.e. price of each unit is $p+=+1%2F2%5E7+%2B+75 = $75.01 (approx).

Try the others as above. The answers are $75 (approx) in both the case.
