If you were to invest only $1, how much simple interest would you have if the rate was 4.6%? Use the following years for each scenario:

30 years:

45 years:

65 years:

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the investment.

P represents the principal or amount invested.

R represents interest rate

T represents the duration of the investment in years.

From the information given,

P = $1

R = 4.6%

1) When t = 30 years,

I = (1 × 4.6 × 30)/100 = $1.38

2) When t = 45 years,

I = (1 × 4.6 × 45)/100 = $2.07

3) When t = 65 years,

I = (1 × 4.6 × 65)/100 = $2.99

Step-by-step explanation:

The table only has values for multiples of 5 years. Of 97,592 females alive at age 40, 91,234 are still alive at age 60. The probability of living those 20 years is ...

  91234/97592 ≈ 0.9349
