You can put this solution on YOUR website!
The bank offers 2.8% simple interest for 3 years. This amounts to 3 x .028, which equals 8.4% over the years. Let your initial deposit be n. Then:
\n" ); document.write( "n(1+.084)=850
\n" ); document.write( "1.084n=850
\n" ); document.write( "n=$784.13 needs to be your initial deposit. ☺☺☺☺\r
\n" ); document.write( "\n" ); document.write( "Simple interest does NOT compound over time; so the bank only pays 2.8% interest per year on the initial deposit. Since the CD is for a 3 year period, the total interest earned is 3 x 2.8%, which is 8.4%. Let n be your initial deposit. Then:
\n" ); document.write( "n(100%+8.4%)=850
\n" ); document.write( "1.084n=850
\n" ); document.write( "n=$784.13 ad your initial deposit. Again. ☺☺☺☺
