To determine which option is the better buy, we can calculate the cost per sandwich for each option.
1. **Option 1: 3 sandwiches for $4.95**
\[
\text{Cost per sandwich} = \frac{4.95}{3} \approx 1.65
\]
2. **Option 2: 4 sandwiches for $6.72**
\[
\text{Cost per sandwich} = \frac{6.72}{4} \approx 1.68
\]
Now we compare the cost per sandwich:
- Option 1: approximately $1.65 per sandwich
- Option 2: approximately $1.68 per sandwich
Since $1.65 is less than $1.68, **Option 1 (3 sandwiches for $4.95)** is the better buy.
