Original ratio of saved to total money per paycheck  = 20 / 200    (10 %)

Final ratio of saved to total money per paycheck  = [ x + 20 ] / [ x + 200 ]

Final amt saved per paycheck =   x + 20

I was wondering, why wouldnt it be x+200 and instead of  x+20? for the final amount?

Remember that  x  is the additonal dollars that she  puts in her savings account aftr she earns \$200.....she contributes \$20 as long as she  only makes \$200

After  \$200, she puts  every  dollar into the account...

So  the final amount she contributes (saves) is 20 + x

And the total amount she makes is  200 +  x

So.....the  ratio of savings / total paycheck  = [ 20 + x ] / [ 200 + x ]

Example ...suppose she eans \$240 dollars

She puts \$40  into the account

So.....the ratio of savings / total paycheck  =  [ 20 + 40 ] / [200 + 40 ] = 60 / 240  = .25  = 25%
