Question 321935: A student has 64 coins worth a total of $9.20. Each coin is either a nickel (5 cents) or a quarter (25 cents). If x is the number of nickels, then x can be determined from the equation Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let nickels be x
quarters will be 64-x
value of coins = 920 cents
..
5x+25(64-x)=920
5x+1600-25x=920
-20x=-1600+920
-20x=-680
x=34 the number of nickels
Balance 64-34=30 are quarters
