Math Problem, need help for a test

11.75% = 0.Amount = 25000(1+0.= 25000(1.= $78308.Cf = Ci (1 + 0.......
The question: Nicole invested 25,000$ in coca cola stocks compounded yearly at a rate of 5% per annum for 25 years, determine the possibly amount of the interest to earn

Would it be 25000x0.05x25

You are NOT correct
It is simple interest

Compound interest = 25000(1+0.05)^25 - 25000
= 84658.87 - 25000
= $59658.87
>>>>>>>>>>>>>>
11.75% = 0.1175
Amount = 25000(1+0.1175/2)^10*2
= 25000(1.05875)^20
= $78308.42

Nicole wants to invest dad's money

Find the final capital ie with the interest
Cf = Ci (1 + 0.05) ^25
Deduct the initial capital Ci = 25000

interests = Cf - Ci
