Myles mows lawns during the summer to earn money. since he is trying to save money for a car, he tries not to spend very much of it. in fact, his goal is to save $5 for every $7 he makes.
if myles made $128 this week, how much can he spend?
$91.43
$3.66
$25.60
$36.57

So: he makes $7 and wants to save $5 for every $7 dollars he makes. Meaning, he is allowing himself to spend $2. Right?
  
  This week, he made $128. We have to multiply by $2 because that's how much he's spending, so:
  
          128*2= 256. Now we divide by 7 because he made that much every time he worked meaning,
             256/7 ≈ 36.6; I rounded.

That would be my answer, do you agree or disagree with me? I hope I helped and if you have any further questions, please don't hesitate to ask.
