44. Chicago Skate Company produces three kinds of roller skates. The cost in dollars for producing x, y, and z units of each, respectively, is c(x, y, z) = 3000 + 27x + 36y + 47z. (a) The value of dc/ax is the change in cost due to a one unit increase in production of the least expensive skate, the levels of pro- duction of the higher-priced units being held fixed. Find it. (b) Find dc/əz, and interpret.

6. A 50 gallons tank initially contains 10 gal of fresh water. At t = 0, a brine solution containing 1 lb of salt per gallon is poured into the tank at the rate of 4 gal/min, while the well-stirred mixture leaves the tank at the rate of 2 gal/min. Find a. the amount of time required for overflow to occur b. the amount of salt in the tank at the moment of overflow
Paul's firm produces the same good as Sal's firm. The total cost of producing qp units in Paul's firm is Cp( qp ) = 8.6 qp + 1.1. The total cost of producing qs units in Sal's firm is Cs( qs ) = 8.6 qs + 1.1. What is the efficiency loss if each person's firm produces half of a total of 523 units?
The yield in bushels from a grove of orange trees is given by Y = x(1000 − x), where x is the number of orange trees per acre. How many trees will maximize the yield?
1. Suppose that a commercial truck has an efficiency of 120 – 2v m(v) miles/gallon going at speed of v miles/hour. The driver's rate is 15 dollars/hr, and gas is $3.50/gal- lon. a. Find the cost C(v) per mile to travel at speed v mph. b. Find the cheapest driving speed.
A tank with a capacity of 25 L originally contains 15 L of brine with a concentration of 5 g/L of salt. Water containing 1 g/L of salt is entering at a rate of 5 L/min, and the mixture is allowed to flow out of the tank at a rate of 4 L/min. Find the concentration (in g/L) of salt in the tank when it is on the point of overflowing.
