How many rolls of dimes do I need to make $40

Question

HOW MANY ROLLS OF DIMES DO I NEED TO MAKE$50

Answer 1

You did not state the number of dimes that make a roll.  Suppose there are n dimes in each roll.  Divide the total amount of money by the dollars in a single roll.  That will give the number of rolls.

 

$40 / (n x $0.10) = ?

 

You can see that without n, we cannot give you a complete answer.
