. If 85 burgers were consumed how many did each person eat?

Question

Snard ate twice as many burgers as Elvis who ate 7 more burgers than Wilma

Answer 1

If you consider x as burgers eaten you get the equation

85=2x(snard)+x(Elvis)+x-7(Wilma)

Combine the xs

85=4x-7 

Add 7 to each side

92=4x

Divide by 4 

23=x

Then using this you can plug the values into the equation above to find out how many each person ate. 

S=46

E=23

W=16
