If chris has 4 times as many nickels as quarters and they have a combined value of 180 cents, how many of each coin does he have?

1 nickel = 5 cents

1 quarter = 25 cents

Let the number of nickels be = n

Let the number of quarters be = q

As mentioned, Chris has 4 times as many nickels as quarters

so, n=4q ----- (1)

The coins have a combined value of 180 cents, so

  ----- (2)

Putting n=4q in equation (2)

Hence, quarters are 4

As, n=4q

Hence, nickels are 16
