p = f(x) = (x/40) + (5/8)

what is the revenue? im confused

anonymous · Answer

I am assuming that the revenue is the value of p, because the equation doesn't make sense otherwise. Normally revenue = price * demand, but in this case the demand is being subtracted from the price. Check to make sure you copied the equation properly.
