Question 995876: at the grocery store, i had 9 coins of the same kind as change. if the value of the coins equaled 2 added to one of the coins, what kind of coins did i receive?
Answer by josgarithmetic(39618)   (Show Source):
You can put this solution on YOUR website! v, the coin value of 1 coin.
9v, the amount of change, being nine coins.
9v=2+v, the value of the (all of them together) coins equals two added to ONE coin.
9v=v+2
9v-v=2
8v=2
v=1/4
This seems off. Bad if v is in cents, but meaning quarter of a dollar if v is in dollars.
