\n" ); document.write( "you borrow $2500 froma friend and promise to pay back $2655 in six months. What simple interest rate will you pay?
\n" ); document.write( "example: A= P (1 + rt)
\n" ); document.write( "2655=2500[1 + r(0.5)]
\n" ); document.write( "2655=2500 + 1250r
\n" ); document.write( "I don't know how they got 1250r (distributive property)

You can put this solution on YOUR website!
2655=2500[1 + r(0.5)]
\n" ); document.write( "2655=2500 + 1250r
\n" ); document.write( "I don't know how they got 1250r (distributive property)
\n" ); document.write( "---------
\n" ); document.write( "The distributive property is a*(b+c)=a*b+a*c
\n" ); document.write( "------------
\n" ); document.write( "You have: 2500*(1+r(0.5))
\n" ); document.write( "It becomes 2500*1 + 2500*r(0.5)
\n" ); document.write( "=2500 + 1250r
\n" ); document.write( "---------
\n" ); document.write( "The 1250r is (0,5)2500r = 1250r\r
\n" ); document.write( "\n" ); document.write( "---------
