Question 32599: George saves nickles and dimes for tolls. If he has 28 coins worth $2.60, how many are nickles and how many are dimes? Answer by Paul(988) (Show Source):
You can put this solution on YOUR website! Let the amount of nickels be x
Let the amount of dimes be y
x+y=28
y=28-x (subsitution)
Dime value x 100 = 10
Nickels value x 100= 5
Total value x 100 = 260
Equation:
5x+10(28-x)=260
5x-10x=260-280
-5x=-20
x=4
y=28-4
y=24
Hence, there are 24 dimes and 4 nickels.
Paul.
