You can put this solution on YOUR website! c = number of 5 cent coins in the roll
---
(5 cents) * c = ( 5 dollars * 100 cents/dollar )
5c = 500
---
c = 500/5
---
Answer:
c = 100

Let n represent the answer, the number of nickels in the roll.
$0.05n = $5.00
Drop the dollar marks
0.05n = 5.00
Multiply both sides by 100 (move the decimals two places to the right)
5n = 500
Divide both sides by 5
=
Cancel the 5's on the left side of the equal sign and divide 500 by 5 on
the right side:
= 500÷5
n = 100

[You might point out that a standard roll of nickels is worth $2, not $5
and it contains 40 nickels not 100, so this is a much longer roll of nickels, times as long as a standard roll.]
