Hi,

Laura found $2.15 in quarters and nickels in the bottom of her purse

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

Solving for x

  30x = 390

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



CHECKING our Answer***

 5*13 + 25*6 = 65 + 150 =  215cents = $2.15
