Best ResponseYou've already chosen the best response.1Try not to write the %, and the brackets at the end are not correct. It should look like this. 254,652=56734(1+0.1025/4)^(4x) How did you solve for x?

Best ResponseYou've already chosen the best response.1The problem is, 14.84 is not the correct answer, because you will see that if you use the same compound interest formula, and solve for FV, you get PhP 254757.28 and not 254652. You need more accuracy.

Best ResponseYou've already chosen the best response.1The reason is you are not solving for the same unknown, you need some adjustments to help the calculator.

Best ResponseYou've already chosen the best response.1We will start by understanding how compound interest works, then we will be able to solve for anything, even when the 991es gets stuck, ok?

mathmate

Best ResponseYou've already chosen the best response.1So the compound interest formula works like this: F=P(1+i/m)^(mt) where F=future value, P=present value, m=number of times it compounds in a year, n=number of years, and i=(nominal) interest rate. I think you are familiar with it, right?

Best ResponseYou've already chosen the best response.1Not too fast, we need to understand, and modify the formula to help the calculator. I was actually surprised that it found the answer the first time around!

Best ResponseYou've already chosen the best response.1The key is to take log on both sides, which then reduces the exponentiation to a multiplication. See if you can come up with a new formula using logs!

Best ResponseYou've already chosen the best response.1You're still using the calculator. I need you to take log on both sides of the formula, and simplify the equation. It will be in a form that the calculator will solve!

Best ResponseYou've already chosen the best response.1Take log on both sides, and change the exponent (on the right of the equal sign) to multiplication, as the laws of exponents require. log(ab)=log(a)+log(b) log(a^b)= b log(a) and put the modified formula for the calculator to solve. Tell me what you get.

Best ResponseYou've already chosen the best response.1You seem to be a factor of approximately 10 off somewhere. Use this interest rate and the compound interest formula to see you you get back 48500 after 85 months. Can you show me what you put in the calculator, perhaps a 12 is missing or misplaced somewhere!

Best ResponseYou've already chosen the best response.1Using interest rate of 4.1254759065 x 10^4, we get only 36105 after 85 monthes.
