(a)
To find: the number of each type of package that should be placed on a train car to maximize revenue.
(a)
Answer to Problem 27PPS
The maximum package is
Explanation of Solution
Given:
Car on a freight can hold
Freight service handle two types of packages which weighs
And a large which are
Concept used:
Graphing the inequalities, it will graph the ordinary linear functions just like it is done before. The difference is that a solution to the inequality is not the drawn line but coordinate plane that satisfy the inequality.
The boundary line is dashed for
Calculation:
Suppose
Then, the optimizing is written as follows.
The constraints are:
The graph is shown below.
The vertices of the feasible region are

(b)
To find: the maximum revenue per train car.
(b)
Answer to Problem 27PPS
It is

Calculation:
The maximum package is
The maximum revenue per train car is
Hence, it is
(c)
To find: whether the maximizing revenue is necessary a best thing company does and explain.
(c)
Answer to Problem 27PPS
It is not necessary to maximize the revenue.

The boundary line is dashed for
Calculation:
the maximizing the revenue is not necessary because of the revenue is maximized the company will not deliver any large packages and customers will large packages to ship will probably choose another carrier.
Hence, it is not necessary to maximize the revenue.

- Directions: Use the equation A = Pet to answer each question and be sure to show all your work. 1. If $5,000 is deposited in an account that receives 6.1% interest compounded continuously, how much money is in the account after 6 years? 2. After how many years will an account have $12,000 if $6,000 is deposited, and the account receives 3.8% interest compounded continuously? 3. Abigail wants to save $15,000 to buy a car in 7 years. If she deposits $10,000 into an account that receives 5.7% interest compounded continuously, will she have enough money in 7 years? 4. Daniel deposits $8,000 into a continuously compounding interest account. After 18 years, there is $13,006.40 in the account. What was the interest rate? 5. An account has $26,000 after 15 years. The account received 2.3% interest compounded continuously.

The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.arrow_forwardPRIMERA EVALUACIÓN SUMATIVA 10.
