Answer:
Therefore the cost of a bag of chips is $0.75
therefore the cost of a cheeseburger is $3.
Step-by-step explanation:
i) let the cost of a cheesburger be x.
ii) let the cost of a bag of chips be y
iii) therefore it is given that x + y = 3.75
iv) it is also given that 2x + 3y = 8.25
v) multiplying the equation in iii) by 2 we get 2x + 2y = 7.50
vi) subtracting the equation in v) from the equation in iv) we get y = $0.75
vii) Therefore the cost of a bag of chips is $0.75
viii) Substituting the value of y found in vii) into iii) we get x = 3.
ix) therefore the cost of a cheeseburger is $3.
