Answer:
Quarter pounder has -580 calories and the Whooper has
1589 calories
Step-by-step explanation:
Let x represent quarter pounders and y represent the Whoppers.
2 QP and 3 Whoppers provide 3607 calories and one of each provide 1009. so let set up the system
[tex]2x + 3y = 3607[/tex]
[tex]x + y = 1009[/tex]
Apply subsitution method
[tex]y = 1009 - x[/tex]
[tex]2x + 3(1009 - x) = 3607[/tex]
[tex]2x + 3027 - 3x = 3607[/tex]
[tex] - x + 3027 = 3607[/tex]
[tex] - x = 580[/tex]
[tex]x = - 580[/tex]
Plug the system back into one of the equations and we get
[tex]y = 1589[/tex]
