You can put this solution on YOUR website!
n the number of nickels as well as the number of dimes
25(12-2n) + 10n + 5n = 125cents
300 - 125 = 35n
175 = 35n
175/35 = n = 5, the number of nickels as well as the number of dimes
2 Quarters12-2%2A5%29
5 Dimes
5 Nickels
And...checking
2•25 + 5•10 + 5•5 = 50 + 50 + 25 = 125cents 0r $1.25
