lubasha [3.4K]

Answer:

The cost of a combo meal is $8 and a salad is $4.

Step-by-step explanation:

You have to form simultaneous equations with the given informations. Let combo meal be m and salad is s :

$m + s = 12 - - - (1)$

$2m + s = 20 - - - (2)$

Next, you have to solve these equations :

$(2) - (1)$

$2m + s - m - s = 20 - 12$

$m = 8$

$sub \: \: m = 8 \: \: into \: \: (1)$

$(1)⇒$

$8 + s = 12$

$s = 4$
