Pls send the options so I can confirm the answer.
9.75-3.50=2.50x
6.25=2.50x
6.25÷2.5=2.50x÷2.5
2.5=x
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
