Nicolet wants to buy a new state of the art computer for R35 000. She decides to save by depositing an amount of R500 once a mon

sineoko [7]

Answer:

54.72 months

Step-by-step explanation:

Given:

Future value = R35,000

Annuity = R500

Interest = 11.32% per year

Interest per month, r = $\frac{11.32}{12}$ = 0.943% = 0.00943

Let 'n' be the total time in months taken

Now,

Future value of annuity is calculated using the formula as:

$\textup{Future value}=\textup{Annuity}\times[\frac{(1+r)^n-1}{r}]$

on substituting the respective values, we get

$35000=500\times[\frac{(1+0.00943)^n-1}{0.00943}]$

$70=[\frac{(1.00943)^n-1}{0.00943}]$

1.6601 = 1.00943ⁿ

taking log both sides, we get

log(1.6601) = n × log(1.00943)

0.22= n × 0.00402

n = 54.72 months
