Question 912640: A person has thirty coins, comprised of nickles and dimes. What is the maximum number of nickels if the total value is at most $2.60? Answer by josgarithmetic(39630) (Show Source):
You can put this solution on YOUR website! d dimes and n nickels.
d+n=30 and 0.1d+0.05n=2.60.
You are not looking for a maximum quantity, but are looking for an exact quantity, unless it is not a whole number.
