A record store is deciding on what price to sell its basic used cds and lps for. The profit model is P(x, y) = e e9x+10y-x²-y²-33 dollars per month where x is the price per cd (in dollars) and y is price per lp (in dollars). To maximize profit the store store should charge: dollars dollars per cd, per lp. The maximum profit earned in a month is: dollars.

The CMO of ABC Company presumed that the demand for a Product Y can be modeled by p=80-0.01y where p is price per unit and y is the no. of units. The cost of producing y units is modeled by C=6000+50y+0.04y^2. What is the price will yield the maximum profit?
In order to treat a certain bacterial infection, a combination of two drugs is being tested. Studies have shown that the duration of the infection in laboratory tests can be modeled by D(x, y) = x2 + 2y2 − 14x − 16y + 2xy + 120 where x is the dosage of the first drug and y is the dosage of the second drug (both in hundreds of milligrams). Find the amount of each drug necessary to minimize the duration of the infection. First drug and second drug in hundred mg.
A manufacturer of lighting fixtures has daily production costs of C = 800 - 30x + 0.75x, where C is the total cost (in dollars) and × is the number of units produced. What daily production number yields a minimum cost?
The construction cost C is directly proportional to the material input (M) and the square of investment (I) and conversely proportional to the labor input (L). Supposing C = 18, when M = 2, I = 6, and L = 4 all in million pesos units, what will be the construction cost in million pesos when L = 6, I = 4, and M = 3?
