Best ResponseYou've already chosen the best response.0You decide to put $175 in a savings account to save for a $3,000 down payment on a new car. If the account has an interest rate of 3% per year and is compounded monthly, how long does it take you to earn $3,000 without depositing any additional funds?

Best ResponseYou've already chosen the best response.3interest rate of 3% per year and is compounded monthly, that means you work in months (not years) and the interest rate is 0.03/12 the equation you want to solve is 175(1+ 0.03/12)^n = 3000 175(1.0025)^n = 3000 1.0025^n= 17.142857

Best ResponseYou've already chosen the best response.01.0025^n=3000/175 n log(1.0025)=log(3000/175) solve for n.

Best ResponseYou've already chosen the best response.3when you find n, it will be in months divide by 12 to get years

Best ResponseYou've already chosen the best response.3what do you get for log(3000/175) ?

phi

Best ResponseYou've already chosen the best response.3so you have n log(1.0025) = 1.23408320603 divide both sides by log(1.0025) n= 1.23408320603/log(1.0025) what do you get for n

Best ResponseYou've already chosen the best response.3if it has a rate of 6% per year, or in this case 6%, as a decimal is 0.06 on a monthly basis, divide by 12: 0.06/12 = 0.005 in percent: 0.5%
