Answer :

Certainly! Let's tackle the problem step-by-step:

1. Understand the Problem:
- Mom needs a dozen eggs.
- A dozen is a common unit of measurement which means 12 items.
- Mom currently has only 1 egg.
- We need to find out how many more eggs Mom should buy.

2. Identify the Known Values:
- Total eggs needed: 12
- Eggs Mom currently has: 1

3. Set Up the Calculation:
- To determine how many more eggs Mom needs to buy, we subtract the number of eggs she currently has from the total number of eggs she needs.
- Formula: [tex]\( \text{eggs\_to\_buy} = \text{eggs\_needed} - \text{eggs\_have} \)[/tex]

4. Perform the Calculation:
- Eggs needed: 12
- Eggs currently have: 1
- Calculation: [tex]\( 12 - 1 \)[/tex]

5. Calculate the Result:
- [tex]\( 12 - 1 = 11 \)[/tex]

6. Conclusion:
- Mom needs to buy 11 more eggs.

Therefore, Mom should buy 11 more eggs to have a total of 12 eggs.
