Jackie's total number of coins is 204.. she has twice as many quarters as nickels and three times as many dimes as nickels.. how many of each coin does she have ? ?
you so much : )

Call x the number of nickles that she has.

Then the number of quarters is twice x = 2x

And the number of dimes is three times x = 3x.

So, the total number of coins is x + 2x + 3x = 240

=> 6x = 240

=> x = 240 / 6

=> x = 40

=> Number of nickels = x = 40

Number of quarters = 2x = 80

Number of dimes = 3x = 120

Verification: 40 + 80 + 120 = 240

nickles 40, quarters 80, and dimes 120.
