Frank noticed that right now his dad, Peter, is five times older than his age. Last year, Frank's age was half that of his brother, John. Nine years from now, Peter will be twice as old as John. What is the sum of the current ages of Frank, John, and Peter?\r
\n" ); document.write( "\n" ); document.write( "So far, I figured that
\n" ); document.write( "Peter = 5(frank)
\n" ); document.write( "Frank = 1/2(john)+1
\n" ); document.write( "John = 2(peter)-9
\n" ); document.write( "

FYI: Five times older is worded incorrectly. It should be five times AS OLD\r

document.write( "\n" );
document.write( "Let Frank’s be F

document.write( "Then Peter’s (Dad’s) is: 5F

document.write( "5F + 9 = 2(2F – 1 + 9)

document.write( "5F + 9 = 2(2F + 8)

document.write( "5F + 9 = 4F + 16

document.write( "5F – 4F = 16 – 9

document.write( "F, or Frank’s age is: 7

document.write( "Peter’s: 5(7), or 35

document.write( "John’s: 2(7) – 1, or 14 – 1, or 13\r
