Problema Solution
The cost of a burger and soda is $8.00. The cost of 6
burgers and 2 sodas and one bag of chips is $34. If the cost
of a burger and one bag of chips is $18.50, how much does
one burger cost?
Answer provided by our tutors
let
b = the cost of one burger
s = the cost of one sods
c = the cost of one bag of chips
the cost of a burger and soda is $8.00
b + s = 8
the cost of 6 burgers and 2 sodas and one bag of chips is $34
6b + 2s + c = 34
the cost of a burger and one bag of chips is $18.50
b + c = 18.50
by solving the system of equations
b + s = 8
6b + 2s + c = 34
b + c = 18.50
we get a negative value for the burger that is
b = - 0.167

the negative cost of the burger means that we don't have to pay for it and additionaly we receive some money back, that is $0.167.
or perhaps there is some mistake with the numbers in text of the problem.
