Based on the calculations, the interest rate on the stock in four (4) years is equal to 7.1%.
<u>Given the following data:</u>
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:
<h3>How to calculate simple interest?</h3>
Mathematically, simple interest can be calculated by using this formula:
I = PRT
<u>Where:</u>
- 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%.

14 and 21
14 + 7 is 21 and 21 + 14 is 35.
Answer:
Solving 
we get 
Step-by-step explanation:
We need to find solution of
Solving the inequality:
Multiply 6 with terms inside the bracket
Subtracting 12 on both sides
Adding 4x on both sides
Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >
So, after solving we get
