molly ran 1/4 of a mile in 1 minute if molly runs at that speed how long will it take her to run 4 miles
Vika [28.1K]

Step-by-step explanation:

Molly ran 1/4 of a mile in 1 minute, i.e.

1/4 mile : 1 minute

Multiply both sides by 4 to get time for one mile

1 mile : 4 minutes

Multiply by 4 again to get time for 4 miles

4 miles = 4*4 = 16 minutes.

So it takes Molly 16 minutes to run four miles.

A new furnace for your small factory will cost $29,000 and a year to install, will require ongoing maintenance expenditures of $
Neporo4naja [7]

Answer:

Net present value is $61,058.

Step-by-step explanation:

Net present value is the difference between present value of cash inflows and the present value cash outflows over the period of time. NPV method is used in capital budgeting to analyze profitability of the project.

Less: initial cost is $29,000

Add: Year 1: Cost saving due to new furnace is $5,600 (2,800 oil gallons * $ 2 per gallon)

Year 2: Cost saving due to new furnace is $7,000 (2,800 oil gallons * $ 2.50 per gallon)

Year 3- 20: Cost saving due to new furnace is $8,400 (2,800 oil gallons * $ 3 per gallon)

Less : Maintenance expenditure is $1,200

The furnace will benefit for 20 years and the price per gallon will increase by $0.50 year.

The annuity factor is applied at discount factor of 6% and then present value of each cash inflow and outflow is calculated. The net present value is $61,058.
