Hi

three times as many nickels as quarters and twice as many dimes as quarters

Let x, 3x, 2x represent number of quarters, nickels and dimes respectively

 25x +  5*3x + 10*2x = 180 cents

solving for s

  60x = 180

     x = 3, the number of quarters. there are 9 nickels and 6 dimes 

 9 nickels the answer requested.

 25*3 + 5*9 + 10*6 = 180 cents or $1.80
