You can put this solution on YOUR website! The total value of a collection of dimes and nickels is $2.70.
If the total number of coins is 39, how many of each type of coin are there?
Number of dimes: x
Number of nickels: (39-x)
10x + 5(39-x) = 270 (cents makes sense)
5x = 75
x = 15, the number of dimes. 24 Nickels
checking = 270cents or $2.70
