I just realized there was some problems with my post. Sorry about that.

Anyway, I think the #1.)answer for a:38, and b:$18,892. I don't know what to do for the rest though.

1.) C(q)=q^3–75q^2+1875q+1070 for 0<q<50 and a price per unit of $500.

^--(These are "equal to" as well)

Round your answers to the nearest whole number.

a) What production level maximizes profit?

q =

b) What is the total cost at this production level?

cost = $

c) What is the total revenue at this production level?

revenue = $

d) What is the total profit at this production level?

profit = $

2.) Suppose the cost function for producing gadgets is C(q)=0.04q^2+5q+44.

At what production level is the maximal profit achieved if each item is sold for 7 dollars? Answer:
