To calculate the total amount including a tip of 23%, Annabelle should first convert the percentage to a decimal.
23% as a decimal is:
\[
0.23 = \frac{23}{100}
\]
Next, to find the total amount including the tip, she needs to add this decimal to 1 (which represents the original amount of the meal). Thus, she calculates:
\[
1 + 0.23 = 1.23
\]
To find the total amount (meal cost plus tip) in one step, she should multiply the cost of the meal by **1.23**.
So, Annabelle should multiply the cost of the meal by **1.23** to find the total amount including the tip.
