Question 20143: Please help me. i don't know how to set it up and solve it.
jamie has a jar of coins containing the same number of nickels, dimes, and quarters. The total value of the coins in the jar is $13.20. How many coins are in the jar?
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
Let "x" be the number of nickels, of dimes, and of quarters.
The value of the nickels is 5x cents.
The value of the dimes is 10x cents
The value of the quarters is 25x cents.
Equation:
Value of nickels + Value of dimes + Value of quarters =1320 cents
5x + 10x + 25x = 1320

Sove for "x". Then you will know the number of each coin.
Cheers,
Stan H.
