Question

A collection of quarters and nickels is worth $14.80.
There are 88 coins in all.

how many of each coin are there?

quarters??
nickels??

Answer 1

There are n nickels and q quarters. The sum of the number of coins is 88:
n+q=88

We also know that each nickel is worth .05 of a dollar and a quarter is .25 of a dollar. So the total value of these n+q coins is

n*.05+q*.25=14.80

There are two equations with two unknowns. Easy to solve:

n=88-q

Then substitute n into second equation and solve for n.

Then take this n and find q:

q=88-n

That's it!

Hope this helps!

Answer 2

@ybarrap That doesn't make sense

Answer 3

ok, let's try it this way, your goal is to come up with two equations you can solve

Answer 4

both equations need to include the number of nickels, let's call it n, and the number of quarters, lets call it q.

Answer 5

So now, you are told you have 88 coins, right? How do they get that number? What do they do?
