Question

question says ; miranda has $3.60 in quarters and nickels in her piggy bank. which equation could be solved to find the possible combinations of quarters and nickels miranda has?

Answer 1

To find the relation between them, you need transform them to the same currency. Let's transform them to cents.
$3.60 = 360 cents.
One quarter is 25 cents, and one nickel is 5 cents.

So 360 = 25q + 5n

Hope this helps! :D
