Question

The cost of 3 tacos and 1 soda is $7. The costof 4 tacos and two sodas is $10. What is the cost of one taco

and one soda?

Answer 1

It would be 3 dollars.

Explanation:

Because you do 3x2 which is the closest to 7 so that means you do 6/3 which is 2 and that means each taco cost 2 dollars and 1 soda is 1 dollar.

Answer 2

cost of tacos=$2

cost of soda=$1

Explanation:

x=price of tacos

y=price of soda

3x+y=7 --> y=7-3x

4x+2y=10 --> y=5-2x

5-2x=7-3x

x=2

y=5-2(2)=1
