I would really appreciate the help .
Im not sure which ones would go where.
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%
