The revenue from the sale of a product is, in dollars,

R = 1500x + 3000(2x + 3)^−1 − 1000
where x is the number of units sold. Find the marginal revenue when 150 units are sold. (Round your answer to two decimal places.)

1 answer

dR/dx = 1500 - 3000*2/(2x+3)^2
if x = 150

dR/dx = 1500 - 6000/303^2

= $1499.93 per unit

the point is that you have an initial 1000 setup cost
then it is $1500 per unit but that decreases as the number goes up and you train robots
