- How do you compute compound interest?
- How do you do compound interest problems?
- What is the formula for compound interest and what does each variable stand for?
- How do you solve for the exponent in an equation?
- How can you check your solution to a compound interest word problem?
- How many years does it take an investment of $4,000 to triple if it is put into a savings account earning 6% interest compound quarterly?
- How do you solve 3 = (1 + .06/4)^4t for t?
This problem is very similar to the previous problem in that another compound interest problem is solved. Again, you are solving for the time variable, which is in the exponent, which means logarithms must be used. All steps are explained very well. Also, the solution is checked to ensure that the solution makes sense in the original question.
