Suppose the supply and demand for a certain textbook are given by supply: p=1/4(q^2)

demand: p= -1/4(q^2) +10

where p is the price and q is the quantity. Find the demand quantity and the supply quantity at a price of $5.

The number of books that are demanded at a price of $5 is [ ] and the number of books supplied at a price of $5 is [ ].
