Answer:

Step-by-step explanation:
We are given that the shorter piece is x
From your description, the longer piece is 2x + 2
The total length is
x + 2x + 2 = 14
ie
3x + 2 = 14
3x = 12
x = 4
So the length of the shorter piece is 4 ft
Therefore the length of the longer piece must be
(14 - 4) ft = 10 ft
Answer:
Builtrite D should purchase the machine
Step-by-step explanation:
Cash outflow in year zero = $ 500,000 + $ 25,000 ( training cost ) + $ 30,000 ( Net working capital)
Cash outflow in year zero = $ 555,000
Terminal cash flow in year 10 = $ 150,000 + $ 30,000 ( NWC)
Terminal cash flow in year 10 = $ 180,000
Operating cash flow per year = [ Savings - expenses - depreciation ] X ( 1 - tax rate) + depreciation
Net present value = 
The Net present value of purchasing the machine = $32,071.42
Builtrite D should purchase the machine
