Final answer:
The equation that matches the given situation is: 4t + 5e = 10.80.
Step-by-step explanation:
The given situation is that Som ordered 4 tacos and 5 enchiladas for lunch and the bill came to $10.80. We need to determine which equation matches this situation.
Let's assume the cost of each taco is 't' and the cost of each enchilada is 'e'.
The equation that matches the given situation is: 4t + 5e = 10.80.
This equation represents the total cost of the tacos and enchiladas, which should equal to the total bill paid by Som.
