In this context, the number 8 represents the total number of meals purchased by the Johnsons (2 burger meals + 5 hot dog meals = 8 meals).

but how does 2 burger meals and 5 hot dog meals equals 8 meals

In the context provided, it is stated that the Johnsons purchased 2 burger meals and 5 hot dog meals. Therefore, if each of the 2 burger meals is counted as one meal and each of the 5 hot dog meals is also counted as one meal, the total number of meals would be 2 + 5 = 7 meals.

In the given context, it seems there is an error in stating that 2 burger meals and 5 hot dog meals would equal 8 meals.

To correctly represent the total number of meals purchased by the Johnsons, we would need to add together the number of burger meals and the number of hot dog meals.

Therefore, 2 burger meals + 5 hot dog meals would equal a total of 7 meals, not 8.

To understand how 2 burger meals and 5 hot dog meals equals 8 meals, let's break it down step by step.

Firstly, we have the number 2 representing the number of burger meals purchased by the Johnsons. This means they bought 2 meals that consisted of a burger each.

Secondly, we have the number 5 representing the number of hot dog meals purchased by the Johnsons. This means they bought 5 meals that consisted of a hot dog each.

Now, if we add the number of burger meals (2) and the number of hot dog meals (5) together, we get a total of 7 meals.

However, note that in the context given, the Johnsons purchased a total of 8 meals, not 7. This could mean that they bought an additional meal that is not specified in the question.

To summarize, based on the given information, we can only account for 7 meals (2 burger meals + 5 hot dog meals). The extra meal that leads to a total of 8 meals is not specified and would require further clarification.
