Problema Solution
A manufacturer of portable radios knows that the weekly revenue produced by selling x radios is given by the equation R=1500p−100p 2 , where p is the price of each radio (in dollars). What price should be charged for each radio if the weekly revenue is to be at least $5400 ?
Answer provided by our tutors
R=1500p−100p^2
we need to find a price for which R >= 5400 or
1500p−100p^2 >= 5400
by solving we find:
6 <= p <= 9
