charlie's piggy bank was filled with dimes and nickel's. he took the money out and counted a total of 419 coins. the coins were worth $36.05. how many nickels were in the piggy bank
..
let the number of nickels be x
dimes will be 419-xvalue equation
..
amount = 3605 cents
5x+10(419-x)=3605
5x+4190-10x=3605
-5x = 3605-4190
-5x=-585
x=117 the number of nickels.
419-117= 302 = number of dimes
..
