4. Builtrite D is considering the purchase of a new machine for $500,000 which would require a $5000 installation charge. Employ
Paraphin [41]

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 = -500,000 + \frac{116,000}{1.15^1} + \frac{116,000}{1.15^2} +...+ \frac{180,000}{1.15^{10}}

The Net present value of purchasing the machine = $32,071.42

Builtrite D should purchase the machine

umka2103 [35]

Answer: 5 milimeters.

The formula for calculate the volume of a rectangular prism is:

V=lwh

Where "V"  is the volume, "l" is the lenght, "w" is the width and "h" is the height.

You know that the volume, the lenght, and the width of this rectangular prism are:

V=750mm^3\\l=15mm\\w=10mm

Substitutute these values into the formula and solve for the the height "h":

750mm^3=(15mm)(10mm)h\\\\h=\frac{750mm}{(15mm)(10mm)}\\\\h=5mm
