Hi,

In a collection of coins, there are 7 less dimes than there are  quarters

Quarters: x

Dimes:  (x-7)

Questions States: value of the collection is $3.85

CENTS makes sense

 10(x-7) + 25x = 385¢

   35x = 455 

     x = 13 Quarters  and there are 6 Dimes   (13-7)

CHECKING our answer***

 = 385¢  0r $3.85

Wish You the Best in your Studies.
