Dazzle Posted February 8, 2014 Share Posted February 8, 2014 I'm clearly not in high school; however, I am practicing my math for a test for the Canadian Forces...and I need your help with this question... Steve has three times as much money invested at 6% than he has invested at 8%. If the total yearly interest is $494.00, how much is invested at 8%? Thanks for the help! Oh and I'd need an explanation/breakdown please, if possible. Thanks Link to comment
GoaltenderInterference Posted February 8, 2014 Share Posted February 8, 2014 I hope I did this right. Let x = the amount of money he invested. 3 times as much money = 3x 6% interest = 0.06 8% interest = 0.08 So the equation would be: 3x(0.06) + x(0.08) = 494 Solve for x x = 1900 3x = 5700 Link to comment

Dazzle Posted February 8, 2014 Author Share Posted February 8, 2014 Yeah, you definitely got it. The answer is/was 1900. But I had no idea how to find that X. Thanks! Now I will study your explanation. I'm truly terrible at these word problems. Link to comment

Caboose Posted February 8, 2014 Share Posted February 8, 2014 AP Calculus student and I can't do word problems like this. Just don't think that way. Link to comment
arowind Posted February 8, 2014 Share Posted February 8, 2014 With word questions you just need to pull out all the numerical info and turn your word problem into a normal problem. Then simply make your unknown or the "Question" of the question X and insert it into whatever the given equation is: this time being (3X) 6%interest(or .06) + (X) 8% interest(or .08) = Total money amount(494).

CatsPajamas Posted February 8, 2014 Share Posted February 8, 2014 math sucks and as species it is in our best interest to avoid using it in anyway. you don't need math to pull a trigger and be a bad ass killing machine I don't know why it would be necessary to join the military. Link to comment

Yeah, but the person programming them sure does. Regardless, math skills are good problem solving abilities to have when in situations where you may not be able to rely on technology. Link to comment
