A car rental agency is considering a modification in its oil change procedure. Currently, it uses a Type X filter, which costs $4.75 and must be
changed every 9,000 miles along with the oil (5 quarts). Between each oil change, one quart of oil must be added after each 500 miles. The
proposed filter (Type Y) has to be replaced every 6,000 miles (along with 5 quarts of oil) but does not require any additional oil between filter
changes. If the oil costs $1.19 per quart, what is the maximum acceptable price for the Type Y filter?
Choose the correct answer below.
A. The maximum acceptable price for the Type Y filter is $29.34.
B. The maximum acceptable price for the Type Y filter is $14.67.
C. The maximum acceptable price for the Type Y filter is $40.45.
OD. The maximum acceptable price for the Type Y filter is $22.01.
A company produces and sells a consumer product and is ableto control the demand by varying the selling price. The approximate
relationship between price and demand is
p = 38+ (2,700/D) - (5000/D²) for D>1
The company is seeking to maximize its profit. The fixed cost is $1,000 and the variable cost is $ 40 per unit.
What is the number of units that should be produced and sold each month to maximize profit?

Jenny Tanaka wants to buy a new car, and the annual gasoline expense is a major consideration. Her present car gets 25 miles per
gallon (mpg), and she is considering purchasing a new car that gets 40 mpg. Jenny now drives about 12,000 miles per year and pays
$3.25 per gallon of gasoline. She therefore calculates an annual gasoline consumption of 480 gallons for her 25 mpg car (12,000
miles/25 mpg) compared to 300 gallons consumed per year for the 40 mpg car (12,000 miles/40 mpg). Since driving the higher-
mileage car would use 180 gallons less per year, Jenny estimates the new car will save her $585 in gasoline expense per year (180
gallons 3 $3.25 per gallon). Suppose Jenny buys the 40 mpg car.
According to economic theory, Jenny's actual annual savings on gasoline will be

- A plant has sufficient capacity to manufacture any combination of four different products (A, B, C, D). For each product, time is required to be invested in four different machines, which is expressed in hours per kilogram of product, as shown in the following table as shown in the following table: (attached image) Each machine has an availability of 60 hours per week. Products A, B, C and D can be sold at $9, $7, $6 and $5per kilo, respectively. Variable labor costs are $2 per hour for machines 1 and 2, and $3 per hour for machines 3 and 4. The material costs for each kilogram of product A are $4. The material costs for each kilogram of products B, C, D and D are $4 each kilogram of products B, C and D are $1.

- EMERGENCY! Production just informed management that one of its five glycol squeezers has been destroyed by a rogue computer virus. Production capability is now only 23000 gallons at most. The squeezer cannot be fixed and IceLess cannot afford a replacement. This breakdown will NOT lower fixed costs. This breakdown will not change variable cost per unit, either. If only 23000 gallons are produced, and the earning target remains $94400 above fixed costs, what price per gallon must now be charged?
