# Finding Present Value In Exercises 67-72, find the present value of the income c (in dollars) over f, years at the given annual inflation rate r. See Examples 6 and 7. c = 450 ,   r = 5 % , t 1 = 10  years

To determine

To calculate: The present value of the income c=450(dollars) over t1=10years at the annual inflation rate of r=5%.

Explanation

Given Information:

The annual rate of inflation is 5%, the income is c=450(in dollars) and the time period is 10 years.

Formula used:

If c represents a continuous income function in dollars per year and the annual rate of inflation is r (in decimal form), then the actual total income over t1 years is given by

Actual income over t1years =0t1c(t)dt

and its present value is given by

Present value=0t1c(t)ertdt

Calculation:

The annual rate of inflation is 5%, i.e. r=0.05

The income c(t)=450

The present value of the income using, Present value=0t1<
