. Suppose you moved to another place where the cost of living was higher, but your job paid more there. If a new job at a different place doubled your income per year but also doubled your cost of living per year, then assuming your income per year-standard of living > 0, would you have more money, less money, or the same amount of money left over than before? Prove your answer.

  • Math -

    let this be the original place
    Income-Expenses=residue savings
    let this be the new place
    2*income-2*expenses= 2(Income-expenses)=2*residue

    so your savings is twice as much.
