Let t, represent one breakfast taco and, m, represent one glass of milk

t represents the number of breakfast tacos, and m represents the number of glasses of milk.

Then t: # of tacos and m: # of glasses of milk would be the correct representation of the 2 variables.

In this case, for example,  2t  + 3 y =  5.15  is the equation that represents this situation. This is because 2 tacos, and 3 glasses of milk cost  $5.15.

Option 1 is the correct answer.
