<PRE><B>Question 941895</B>
no of dimes  = 3 times the no of nickles
 10 dimes  = 1 dollar
  1  dime  = 0.1 dollar
20 nickels  = 1 dollar
1 nickle  =0.05 dollar
 total  = $36.05
let x be the no of nickles 
 then no of dimes  = 3x
  3x*0.1 +x*0.05 =36.05
   0.3x+0.05x=36.05
  x(0.3+0.05) =36.05
 x(0.35)= 36.05
 divide with 0.35 on both sides
 {{{ x(0.35)/0.35 = 36.05/0.35}}}
 x= 103
 No of nickles  = 103
 no of dimes  = 3*103
           = 309
Result :no of dimes  =309
 no of nickles  = 103
