If a special sandwich needs 10% more lettuce than the regular version, and the regular version uses 2 ounces, how much lettuce is needed for the special sandwich?

To determine the amount of lettuce needed for the special sandwich, start with the regular amount, which is 2 ounces. The problem states that the special sandwich requires 10% more lettuce than this regular amount.

To calculate 10% of 2 ounces, you multiply:

[

10% \text{ of } 2 = \frac{10}{100} \times 2 = 0.2 \text{ ounces}

]

Now, you need to add this additional amount to the original 2 ounces to find the total amount of lettuce for the special sandwich:

[

2 \text{ ounces} + 0.2 \text{ ounces} = 2.2 \text{ ounces}

]

Thus, the amount of lettuce required for the special sandwich is 2.2 ounces. This aligns precisely with the correct answer, which provides a clear application of the concept of proportions and percentage increase. The choice confirms that understanding how to calculate percentages and applying them to the original quantity is essential for solving the problem accurately.
