Question

Johnny had $12.25 in quarters. He went to the laundromat and spent all of his quarters doing laundry.

If n was the number of quarters Johnny had before he spent them, which equation below could be used to find out the value of n?

Answer 1

12.25 * 4 = n

Answer 2

Thanks D35TR0Y3R

Answer 3

I think it's
12.25/0.25=n
Because each quarter is 0.25

Answer 4

If you want a formula, it would be (money) * (how many of the coin would make a dollar) = amount of coins
