Question 193645: Joe has a collection of nickels and dimes that is worth $6.05. If the number of dimes was doubled and the number of nickels was decreased by 10, the value of the coins would be $9.85. How many dimes does he have? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! If nickels are decreased by 10 then 6.05-.50=$5.55 remains.
9.85-5.55=4.30 or 43 dimes have been added. Since this is a doubling of the dimes he has 86 dimes.
