One week, Huang ordered 1 pizza and 2 sodas for $12. The next week, he ordered 3 pizzas and 4 sodas from the same restaurant for $30. Write and graph a system of equations to determine the cost of each pizza and the cost of each soda from this restaurant.
Let x = the cost of a pizza
Let y = the cost of a soda

A pizza costs $8 and a soda costs $4.

A pizza costs $6 and a soda costs $3.

Individual costs cannot be determined. There is no solution.

There are many possible costs for each. There are infinitely many solutions.
