Answer:

 

Step-by-step explanation:

present value of dividend for three years =

2.50 x 1.2 / 1.15 + 2.5 x 1.2² / 1.15² + 2.5 x 1.2³ / 1.15³

= 2.6087 + 2.722 + 2.84

= 8.17

present value of future cash flow after three years

= 2.5 x 1.2³ x 1.08 / .15 - .08

66.65

present value

= 66.65 / 1.15³ = 43.823

Total present value = 43.823 + 8.17

= 52 approx .

Answer:

at matilda's new job, she will make a rounded salary of $69,000 per year.

Step-by-step explanation:

when solving a problem like this, you have to take her current salary ($64,000 per year) and multiply it to the salary increase percentage by first turning the percentage into a decimal. to turn the percentage into a decimal, you imagine a tiny dot to the right of the 8 like this:

8.

and then you have to move that little dot to the left two times recreating it into .08. you multiply .08 (the salary increase percentage) by her current salary ($64,000) and then also add that number to matilda's current salary to come up with the answer you can round. I'll give you an example of my proscess just so I can give a clear visual of my explanation.

step one:

$64,000

x .08

-------------

5,120

step 2:

$64,000

+$5,120

-------------

$69,120

step 3:

$69,120 is rounded up to the nearest thousands is approximately $69,000

answer: $69,000
