profit = revenue - cost
revenue = price * quantity. So,

p(x) = x(500-x)-35x

Now just plug in your data

Oops mixed up price and quantity

p(x) = x(500-x)-35(500-x)
= (x-35)(500-x)

assuming no extra dolls are made...

For a certain product, the revenue is given by
R = 30x
and the cost is given by
C(x) = 10x + 1700.
To obtain a profit, the revenue must be greater than the cost. For what values of x will there be a profit?
