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

Find the largest rational number r for which 5r ≤ 33.

soldier1979 [14.2K]

Answer:

33/5 or 6.6

Step-by-step explanation:

Well the most 5r can be is 33, since it has the underline under it, so it's less than or equal to.

So set 5r equal to 33

5r = 33

Divide both sides by 33

r = 33/5

You can leave it in this form or convert it to a decimal which is 6.6
