Did I get this right?
natima [27]

Answer: Yes, the answer is 40 quarters.


Step-by-step explanation:

1. You need to remember that 4 quarters make a dollar.

2. Keeping this on mind, you can make a Rule of three, as following: If there are 4 quarters in 1 dollar, how many quarters are in 10 dollars?

Then:

4 quarters-------1 dollar

          x---10 dollars

x=\frac{(10dollars)(4quarters)}{1dollar}\\x=40quarters

3. Therefore, there are 40 quarters in one roll.
