monopoly question doubt

bhavya jain
someone plz tell how to solve this one..
A monopolist faces the demand curve q = 90 - p/2, where q is the number of units sold and p is the price in dollars. She has quasi-fixed costs, C, and constant marginal costs of $20 per unit of output. Therefore her total costs are C + 20q if q > 0 and 0 if q = 0. What is the largest value of C for which she would be willing to produce positive output?

did u ppl solve this way;
Q*=40, p*=100. putting these values in profit function, we get profit=3200-C.....
