To determine who makes a spicier sauce, we can calculate the spiciness ratio of chipotle sauce to the total sauce for both Emma's dad and Uncle Pete.
Emma's dad:
- Chipotle sauce: 8 tablespoons
- Mayonnaise: 12 tablespoons
- Total sauce = 8 + 12 = 20 tablespoons
Spiciness ratio = (Chipotle sauce) / (Total sauce) = 8 / 20 = 0.4
Uncle Pete:
- Chipotle sauce: 6 tablespoons
- Mayonnaise: 10 tablespoons
- Total sauce = 6 + 10 = 16 tablespoons
Spiciness ratio = (Chipotle sauce) / (Total sauce) = 6 / 16 = 0.375
Now, comparing the spiciness ratios:
- Emma's dad's sauce has a spiciness ratio of 0.4.
- Uncle Pete's sauce has a spiciness ratio of 0.375.
Since 0.4 > 0.375, Emma's dad makes a spicier sauce.
The answer is A. Emma's dad makes a spicier sauce.
