Question 220361
I'm assuming that you're using simple interest.



{{{A=P+Prt}}} Start with the simple interest formula.



{{{A=50+50*0.06*50}}} Plug in {{{P=50}}} (the investment), {{{r=0.06}}} (the decimal equivalent of 6%), and {{{t=50}}}.



{{{A=50+50*3}}} Multiply {{{0.06}}} and {{{50}}} to get {{{3}}}.



{{{A=50+150}}} Multiply {{{50}}} and {{{3}}} to get {{{150}}}.



{{{A=200}}} Add {{{50}}} to {{{150}}} to get {{{200}}}.



So if you invest $50 at an interest rate of 6%, you'll have $200 in the account after 50 years.
