. 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.
let this be the original place
let this be the new place
so your savings is twice as much.
