Based on the calculations, the interest rate on the stock in four (4) years is equal to 7.1%.
Given the following data:
Amount borrowed (Principal) = $22,000.
Simple interest, I = $78.40.
Time = 4 year.
To determine the interest rate on the stock in four (4) years:
How to calculate simple interest?
Mathematically, simple interest can be calculated by using this formula:
I = PRT
Where:
- S.I is the simple interest.
- P is the principal or starting amount.
- T is the time measured in years.
Making R the subject of formula, we have:
R = I/PT
Substituting the given parameters into the formula, we have;
R = 6260/(22,000 × 4)
R = 6260/(88,000)
Interest rate = 0.071 = 7.1%.
