Cloe Leon · Answer 1

The burgers cost $5, the fries cost $3, and the sodas cost $2.

Step-by-step explanation:

The fry-less meal has 4 of (1 burger + 1 soda) and is $28. This means ...

1 burger + 1 soda = $7

This observation eliminates choices 1 and 3.

__

The family meal has 2 of (1 burger + 1 fries) and 2 of (1 burger + 1 soda). We know the cost of the latter is 2*$7 = $14, so the cost of the former is $30 - 14 = $16. That means ...

1 burger + 1 fries = $8

This observation eliminates choice 2.

__

The individual item cost is given by choice 4:

The burgers cost $5, the fries cost $3, and the sodas cost $2.
