Answer:
The interest earned at the end of the month is $52.50
Explanation:
Given:
Principle = $1000
Rate of interest = 5.25% per month.

Now we have to find the interest earned end of the month.
We can use the following formula.
Interest = p*r*t where p is the principle, r is the rate and t is the time.
= 1000*0.0525 * 1
= $52.50
The interest earned at the end of the month is $52.50
