Answer:
250 hamburgers were sold on Sunday
Step-by-step explanation:
Let h be the number of hamburgers and c be the number of cheese burgers, then according to given statements, the equations will be:
[tex]h+c = 567\ \ \ \ Eqn\ 1\\c = h+67\ \ \ Eqn\ 2[/tex]
We can use the substitution method to solve the given system of equations.
Putting c= h+67 in equation 1
[tex]h+h+67 = 567\\2h+67 = 567\\2h = 567-67\\2h = 500\\\frac{2h}{2} = \frac{500}{2}\\h = 250[/tex]
Putting h=250 in equation 2
[tex]c = 250+67 = 317[/tex]
Hence,
250 hamburgers were sold on Sunday
