Question

If 2 tacos and 4 drinks cost $16, and 3 tacos and 2 drinks cost $16, how much does a taco cost?

Answer 1

$4 is the cost of a taco.

Step-by-step explanation:

The equation will be,

→ 2x + 4y = 16

→ 4y = 16 - 2x

→ y = (16 - 2x)/4

Now the cost of a taco will be,

→ 3x + 2y = 16

→ 3x + 2[(16 - 2x)/4] = 16

→ 3x + 8 - x = 16

→ 2x = 16 - 8

→ x = 8/2

→ [ x = 4 ]

Therefore, the cost is $4.
