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

or

NPV = $ 17,200,000

The sum of the digits of a two-digit number is 5. If the number is multiplied by 3, the result is 42. Write and solve a system o
Elenna [48]
A two digit number has a tens digit and a ones digit.
Let's say x = tens digit and y = ones digit

"The sum of the digits is 5"
x + y = 5

The next phrase is "the number multiplied by 3 is 42" but we need to represent the number using the digits. So they need to be multiplied first by their place value and added together. [Example: 34 = 3(10) + 4(1)]

The number is: 10x + y
3(10x + y) = 42

The system of equations: (two equations for two unknowns)
x + y = 5
30x + 3y = 42

Then you can use substitution or elimination to combine and solve.
I'll use elimination, multiply the entire top equation by -3 and add the equations together. y will cancel out

-3x - 3y = -15
30x + 3y = 42
------------------
27x + 0 = 27
x = 1

then plug x = 1 into either equation to find y

1 + y = 5
y = 4

remember the x and y represent digits so the number xy is 14
