Help please- Annuities - Find Time of Investment Algebra Two

Mathematics
1 answer:
suter [353]2 years ago
5 0

Based on the calculation below, the number of years it would be for Mia to have $34,000 is 29.1 years.

<h3>How do we find the period or time of investment?</h3>

The formula in the question is the formula for calculating the future value of an ordinary annuity and it can be rewritten as follows:

A = d((((1 + i)^n) – 1) / i) …………………………… (1)

Where:

A = $34,000

d = $850

i = 0.4% * number of months in a year = 0.4% * 12 = 4.8% = 0.048

n = number of years?

Substitute all the values into equation (1) and solve for n, we have:

$34,000 = $850((((1 + 0.048)^n) - 1) / 0.048)

$34,000 / $850 = (((1 + 0.048)^n) - 1) / 0.048

40 = (((1 + 0.048)^n) - 1) / 0.048

40 * 0.048 = ((1 + 0.048)^n) – 1

1.92 + 2 = (1 + 0.048)^n

3.92 = 1.048^n

Taking the log of both sides, we have:

Log3.92 = nlog1.048

0.593286067020457 = n 0.0203612826477079

n = 0.593286067020457 / 0.0203612826477079

n = 29.1379515370189

Rounding to the nearest of a year, we have:

n = 29.1
