Steps to Solve
- Determine the value in cents for 2 dollars
We know that 1 dollar is equivalent to 100 cents, so 2 dollars is equivalent to 200 cents.
$$ 2 \text{ dollars} = 2 \times 100 = 200 \text{ cents} $$

One nickel is worth 5 cents.
- Divide the total value by the value per nickel
To find out how many nickels make up 200 cents, we divide the total cents by the value of one nickel.
$$ \frac{200 \text{ cents}}{5 \text{ cents per nickel}} = 40 \text{ nickels} $$
To make 2 dollars, you need 40 nickels.
