Jennifer had five times as many quarters as dimes.  If the total value of her coins was $16.20, how 

       many of each kind of coin did she have?

No of dimes =x

No of quarters =5x

x*0.1+5x*0.25 =16.20

x*1.35 =16.20

x= 16.2/1.35=12

5x =60

No of dimes =12 value  =$1.20

No of quarters =60 Value + $15

Total value =$16.20
