Hi,

total of 11 coins (quarters + nickles = 11)

how many  of the coins are nickles

Number of Quarters 

CENTS makes sense

 25(11-x) + 5x = 155¢

  25•11 - 25x +5x = 155

  25•11 - 155 = 20x

       120 = 20x

         6 = x, the number of Nickels.  The number of Quarters is 5.   

CHECKING our answer***

 5•25 + 6•5  = 155¢   0r $1.55

Wish You the Best in your Studies.
