Answer:
The freezing point of the water with the added potassium is 24 degrees Fahrenheit.
Step-by-step explanation:
To find the freezing point of the water with the added potassium, you need to subtract 8 degrees from the initial freezing point of water, This is because you know that after adding potassium to water, the freezing point went down by 8 degrees Fahrenheit. So you need to subtract 8 degrees from the initial freezing point of water (32 degrees Fahrenheit). 32º F - 8º = 24º F. So the freezing point of the water with the added potassium is 24 degrees Fahrenheit.
1. Your cash flow is as follows.
initial outlay: $63.75*100 +200.00 = $6575
quarterly dividend: $0.50*100 = $50 . . . for 19 quarters
income from sale: $48.63*100 -200.00 +50.00 = $4713
A suitable financial calculator computes the IRR as -3.23% per year.
2. Your cash flow is as follows.
initial income/outlay: 0
monthly income: $2750 . . . for 48 months
monthly income: $3000 . . . for 36 months
applicable interest rate: .09/12 = 0.0075 . . . per month
A suitable financial calculator computes the NPV as $176,415.70.
