Carson Trucking is considering whether to expand its regional service center in? Mohab, UT. The expansion requires the expenditu

cupoosta [38]

Answer:

NPV = $ 17,200,000

Step-by-step explanation:

Total expenditures = $ 11,000,000

Net cash inflow = $ 3,000,000 per year

total duration of cash inflow = 9 years

Thus, total cash inflow = $ 3,000,000 per year × 9 years = $ 27,000,000

salvage value = $ 1.2 million = $ 1,200,000

NPV = Salvage value + total cash flow - Expenditures

on substituting the values, we get

NPV = $ 1,200,000 + $ 27,000,000 - $ 11,000,000

NPV = $ 17,200,000

There are blue, red and green pencils in the box—20 pencils total. There are 6 times more green pencils than blue pencils. There

lana [24]

Answer:

You have to take 15 pens to get at least one red pencil.

Step-by-step explanation:

If there were one red and 6 green pens, there would be more red than green pens.

If there were 3 or more blue and thus 18 or more green pens, the number of pens would be over 20.

So there must be 2 blue, 12 green and thus 6 red pencils. So you have to take at least 15 pens to be sure that you got a red one.
