Answer:

The correct option is d. Project B.

Step-by-step explanation:

Note: See the attached excel file for the calculation of the Cumulative Cash Flows of Projects A and B.

Payback period refers to the number of time or period that is needed to recoup the amount of money spent a project. The

payback period rule states that when considering two or more projects, a project with the shortest payback period should be selected.

Payback period can be calculated as follows:

Payback period = Time before full recovery + (Unrecovered cost at start of the time of full recovery / Cash flow during the time of full recovery) ………………. (1)

Using the information in the excel file (in red color), equation (1) can be calculated for Project A and Project B as follows:

Project A payback period = 2 + ($1,000 / $3,000) = 2.33

Project B payback period = 2 + ($3,000 / $10,000) = 2.30

Since the payback period of Project B payback period which is 2.30 is lower than the Project A payback period of 2.33, Project B should be selected.

Therefore, the correct option is d. Project B.

Maria is 19 years old. Her age is 4 more than 3 times some number, x.
musickatia [10]

Answer: x = 5

Step-by-step explanation:

We can set up an equation to solve for x:

3x  + 4 = 19

We can subtract 4 from both sides:

3x = 15

We can divide both sides by 3:

x = 5

The total cost 95 pens and 89 notebooks is RS 7434.The total cost of 1 pen and 1 notebook is 81.What the cost of 1 notebook?
Alex

Answer:

The cost of 1 note book = Rs 43.5

Step-by-step explanation:

Given in question as :

95 pens (P) + 89 notebook (N) total cost = Rs 7434

1 pen (P)     +  1 (N)                      total cost = Rs 81

So, from above equation

95 pens (P) + 89 notebook (N) total cost = Rs 7434

1 × 95 pen (P)  +  1× 95 notebook (N)  total cost = Rs 81 × 95

Or, (95 pens (P) + 95 notebook (N) ) - (95 pens (P) + 89 notebook (N) ) = (7695 - 7434)

Or , 6 N = Rs 261

Or,    N =\frac{261}{6} = Rs 43.5

Hence the cost of 1 notebook is Rs 43.5  Answer
