$9,500 is invested at 9% annum simple interest for five years.

a)what is the amount of simple interest payable?
b)calculate the amount accruing for the investment

To calculate the simple interest and amount accruing for the investment, we will use the formulas:

Simple Interest = Principal * Rate * Time
Amount Accruing = Principal + Simple Interest

a) To find the amount of simple interest payable, we can use the formula:

Simple Interest = Principal * Rate * Time

Given:
Principal = $9,500
Rate = 9% per annum
Time = 5 years

First, convert the rate from a percentage to a decimal by dividing it by 100:
Rate = 9/100 = 0.09

Now, substitute the values into the formula:
Simple Interest = $9,500 * 0.09 * 5

Calculate the simple interest:
Simple Interest = $9,500 * 0.45
Simple Interest = $4,275

Therefore, the amount of simple interest payable is $4,275.

b) To calculate the amount accruing for the investment, we can use the formula:

Amount Accruing = Principal + Simple Interest

Given:
Principal = $9,500
Simple Interest = $4,275

Substitute the values into the formula:
Amount Accruing = $9,500 + $4,275

Calculate the amount accruing:
Amount Accruing = $13,775

Therefore, the amount accruing for the investment after 5 years is $13,775.
