So your boss calls you in and says you're doing a great job. He's willing to give you a 3% raise. But here's the catch: From now on, on payday, you're going to get a big bag of random change instead of a check. It'll all be there, plus 3% of what you normally make. But it will be a random assortment of pennies, dimes, nickles, a few quarters, and the occasional canadian penny.
So if you used to make $500(roughly $26,000 a year a week), you now make $515 a week(roughly $26,780). In change.
Would you take the raise? Those coin-to-cash machines typically take 6-8%. And your bank makes you bring in all your change in rolls. Is it worth your time to sit there and roll up change all the time? Do you even make enough money that it's worth buying the rolls? If not, what percentage of a raise would be enough for you to accept change as your pay?
