Thread: need help solving a demand function

The demand for a certain fraternity's plastic brownie dishes is q(p) = 360,000 − (p + 1)2
where q represents the number of brownie dishes that the fraternity can sell each month at a price of p¢. Determine the number of brownie dishes the fraternity can sell each month if the price is set at 60¢.

Since you know that value of p just evaluate the function

I was doing that but general knowledge led me to believe that 60cents is the same as 0.60. That is where I had my problem.
