The revenue obtained from the sale of q units of a product is given by :

R= 30q-(0.3q^2)

A) How fast does R change with respect to q when:

q=10

B) Find the relative rate of change of R, and to the nearest percent, find the percentage rate of change of R.

dR/dq = 30 - .6q
so when q = 10
dR/dq = 30 - .6(10) = 24
Oh! So, then the relative rate is: R1/R = 30-.6q/30q-(0.3q^2) ?
Which is 9%?
