How many nickels and quarters did she find?
There were seven fewer quarters than nickels
Let x, (x-7)represent the number of nickels and quarters respectively
.Question states*** CENTS makes sense
 5x + 25(x-7) = 215 cents

  30x = 390
    x = 13, the number of nickels.  there were 6 Quarters (13-7)
