math

To start you can use variables to represent the different quantities. For example, you can use s for the number of sodas and h for the number of hot dogs.

You can then create equations using these variables.

You know that in total you have 198 sodas and hot dogs so you can write:

s + h = 198

You also know that the number of sodas is equal to two times the number of hot dogs:

s = 2 * h

You can then substitute the second equation into the first one so that it only has one variable

(2 * h) + h = 198

You can then solve for h

(2 * h) + (1 * h) = 198

3 * h = 198

h = 198 / 3

h = 66

You can then use the second equation we found the find the value of s

s = 2 * h

s = 2 * 66

s = 132

You can then plug your values for s and h into the first equation to check your answer

s + h = 198

132 + 66 = 198

198 = 198

This is how you get an answer of 132 sodas and 66 hot dogs
