The marginal profit function for hard disks produced by the Elephant Media Company is given by
80r
MP(r) =
0<r< 100
V + 576
where r is the number of hard disks produced in a work shift and MP(r) is the marginal profit in
dollars.
(i) Evaluate and interpret MP(7).
(ii) Evaluate
MP(r) dr and interpret.
(iii) Knowing that the Elephant Media Company breaks even when 32 hard disks are sold, recover
the profit function P.
