Fab Jeans presently sells ladies' jeans at an average price of $50 a pair,with sales averaging 300 pairs daily. From an analysis of the market, it is estimated that with every $1.50 decrease in the cost of a pair of jeans, daily sales will increase by 25 pairs.
What price should Fab Jeans change to maximize their daily revenue ? What is the maximum revenue ?
Let "x" be the number of decreases of $1.50:
Revenue = price*# of sales
Revenue = (50-1.5x)(300+25x)
Simplify:
Rev = 15000+1250x-450x-37.5x^2
Rev = -37.5x^2+800x+15000
Maximum Revenue occurs when x=-b/2a = -800/-75 = 10 2/3
Rounding up: closest to max occurs when x = 11
That price would be 50-11*$1.5 = $33.50
Revenue at that price would be $19,266.67
--------------------------------
If it costs Fab Jeans $12 to make each pair of ladies jeans, what price should the company charge in order to make the greatest profit ?
----------------
# of jeans sold when Rev is max is 300+25x = 300+25*11 = 575
If each one costs $12 to make that is $6900
Subtracting that from the maximum revenue leaves a profit of $12366.67
