Alison has $1.60 worth of nickels and dimes in her coin purse. she has 11 more nickels than dimes. how many of each coin does she have? enter your answers in the boxes. and

Let the number of nickles be x and the number of dimes be y, so that means

0.05x + 0.1y=1.6

5x+10y=160...1

x=y+11...2

Put 2 into 1 that would give you

5(y+11)+10y=160

5y+55+10y=160

15y=160-55=105

y=105/15=7

x=7+11=18

So she has 18 nickels and 7 dimes
