Answer:
Explanation:
To find the simple interest, we can use the formula:
I = Prt
where:
I = simple interest
P = principal amount
r = interest rate per period
t = time period
Here, P = $1050, r = 3% per annum, and t = 4 months.
First, we need to convert the annual interest rate to a monthly rate:
3% per annum = 3/12% per month = 0.25% per month
Now, we can substitute the values into the formula:
I = 1050 * 0.0025 * 4
= $10.50
Therefore, the simple interest on $1050 for 4 months at the rate of 3% is $10.50.
