3. A company manufactures two types of products: A and B. Three resources R1, R2, and R3 are required to make these products. a.

Each unit of product A requires 8 units of R1 and 4 units of R2. b. Each unit of product B requires 2 units of R1, 5 units of R2, and 3 units of R3. The availabilities of resources R1, R2, and R3 are 500, 400, and 180, respectively. The manufacturer also makes a profit of $20 and $50 for products A and B, respectively. Formulate a linear programming problem whose solution will tell the manufacturer how to maximize the total profit. • What are the decision variables? • What is the objective? • What is the objective function? • What are the constraints?

Answer:

(i)The units of production of Product A and B (x and y) are the decision variables

(ii)Objective is to maximize profit

(iii)Objective function, Max P=20x+50y

(iv)The Contraints are:

8x+2y\leq500....(i)

2x+5y\leq400.......(ii)

3y\leq180

x>0, y>0

Explanation:

Let the number of Product A=x

Let the number of Product B=y

Each unit of product A requires 8 units of R1 and 4 units of R2.

Each unit of product B requires 2 units of R1, 5 units of R2, and 3 units of R3

The availabilities of resources R1, R2, and R3 are 500, 400, and 180

Since R1 \leq500,

Product A requires 8 units of R1 per production unit

Product B requires 2 units of R1 per production unit

Total Unit of R1 possible is given by the inequality: 8x+2y\leq500....(i)

Since R2 \leq400,

Product A requires 2 units of R2 per production unit

Product B requires 5 units of R2 per production unit

Total Unit of R2 possible is given by the inequality: 2x+5y\leq400....(ii)

Since R3 \leq180,

Product B requires 3 units of R2 per production unit

Total Unit of R2 possible is given by the inequality: 3y\leq180....(iii)

Since the manufacturer also makes a profit of $20 and $50 for products A and B, our objective is to maximize profit

Therefore: Objective function, Max P=20x+50y ......(iv)

Project Q has an initial cost of $211,415 and projected cash flows of $121,300 in Year 1 and $176,300 in Year 2. Project R has a
vlada-n [284]

Answer:

Project Q should be accepted.

Explanation:

In this question, we have to use the profitability index formula which is shown below:

Profitability index = Present value of all years cash flows ÷ Initial investment

where,

Present value of cash inflows is calculated by applying the discount rate which is presented below:

For this, we have to first compute the present value factor which is computed by a formula

= 1 ÷ (1 +rate) ∧ number of year

number of year = 0

number of year = 1

Number of year = 2

So,

For year 1 = 0.9216 (1 ÷ 1.085) ∧ 1

For year 2 = 0.8495 (1 ÷ 1.085) ∧ 2

Now, multiply this present value factor with yearly cash inflows

So

For Project Q,

The present value of year 1 = $121,300 × 0.9216 = $111,797.235

The present value of year 2 = $176,300 × 0.8495 = $149,758.967

and the sum of all year cash inflow is 261,556.202

So, the Profitability index would be equal to

= $261,556.202 ÷ $211,415

= 1.23

For Project R,

The present value of year 1 =  $187,500 × 0.9216 = $172,811.059

The present value of year 2 = $236,600 × 0.8495 = $200,981.121

and the sum of all year cash inflow is $373,792.180

So, the Profitability index would be equal to

= $373,792.180 ÷ $415,000

= 0.90

Since, the Project Q has high profitability index than Project R, so Project Q should be accepted.

The correct answer is medicine.
Obviously, any type of disorder or illness of the body has to do with medicine and the possible ways to cure those complications. Hypertension refers to elevated blood pressure levels, so psychology, sociology, and management have nothing to do with it.

Using the aging method of accounts receivable method, $5,000 of the company's Accounts Receivable are estimated to be uncollecti
gogolik [260]

Answer:

The correct answer is $4,500.

Explanation:

According to the scenario, the given data are as follows:

Uncollectible Account receivable = $5,000

Account receivable balance = $100,000

Allowance for Doubtful Accounts = $500

Credit sales = $150,000

So, we can calculate the bad debt expense by using following formula:

Bad debt expense = Uncollectible Account receivable - Allowance for Doubtful Accounts

by putting the value, we get

Bad debt expense = $5,000 - $500

= $4,500.
