Cost of ordering and transporting components for gadgets is given by c(x)= 100(200/x^2 + x/x+30) x is order size in hundreds, c is measured in thousands of dollars. demand function for gadgets is modeled by p = 56e^-.12x where p is the price per unit and x is number of units1. find function r(x) that would give revenue in dollars per unit? 2. build first derivative chart for r(x) (revenue) and give intervals where revenues are increasing and decreasing? 3. how many units will yield maximum revenue? 4. what will price per unit be when revenue is maximum? 5. what will the maximum revenue be?
