You can put this solution on YOUR website! "Mia has twice as many quarters as she has dimes. If she has $3.60 total, how many of each type of coin does she have?"
x = number of dimes
2x = number of quarters {twice as many quarters as dimes}
25(2x) + 10x = 360 {value of coins x number of coins equals total value}
50x + 10x = 360 {multiplied 25 by 2x}
60x = 360 {combined like terms}
x = 6 {divided both sides by 60}
2x = 12 {substituted 6, in for x, into 2x}
she has 6 dimes and 12 quarters
