Let h be hamburgers and c be cheeseburgers.
We know that
We also know that
This gives us a system of equations we can solve. My preferred method to solve systems is substitution, where we solve one equation for one of the variables, then substitute that solution in the other equation, reducing it to a single variable equation. One of the equations already equals h, so we can go straight into the sub part.
Finally, we go back to the other equation and solve for h.
So, total there were 253 cheeseburgers sold, and 325 hamburgers sold.

Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Solve for z
Divide by 8 both sides
The solution for z is the interval ----> (-∞,2]
All real numbers less than or equal to 2
In a number line the solution is the shaded area at left of z=2 (closed circle)
using a graphing tool
see the attached figure
