Question

Need help with 41.

demand function:
3000
f(n) = 4 +
(100 ≤ n ≤1500)
n + 100
where n is the number of tee shirts that can be sold per month
at a price of f(n) dollars per shirt.
41. At a price level of $19 per shirt, compare the predictions
for monthly sales obtained using each model. Hint: You
need to solve each of the equations p(n) = 19 and f(n) = 19
and interpret the results.
42. Show that at a price level of $10 per shirt, the model p
predicts more than twice as many sales per month as does
the model t
Hint: Solve each of the equations n(n) = 10
