Question

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?



nickles and
dimes

Answer 1

32 nickles and 42 dimes

Answer 2

Answer: here

Step-by-step explanation:

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
