Jim and abby each bought burgers and fries from the concession stand at the fair. jim bought 3 burgers and 2 orders of fries for $17. abby bought 2 burgers and 4 orders of fries for $18.
based on the information above, how much did the concession stand charge for each burger?
how much did it charge for each order of fries?

Burger = $4

Fries = $2.5

Step-by-step explanation:

Let price of fries be f and price of burgers be b

We can write the first equation as:

and 2nd equation as:

Let's multiply the first equation by (-2), so we have:

Now we add up this equation and 2nd equation and eliminate f and solve for b first:

Now using b = 4 and putting in the first equation, we can solve for f:

Hence, each burger costs $4 and each fries cost $2.5
