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.

Step-by-step explanation:
there u go mate
Jairo spent $40.18 on 3 music CDs.
Let’s solve for the original prices of each CDs.
=> The sales tax added is 2.33 dollars
=> 40.18 dollars – 2.33 dollars
=> 37.85 dollars
he used 1.00 dollar coupon during his purchase
=> 37.85 + 1.00 = 38.85 dollars
=> now, we need to divide this amount to 3 for 3 CDs
=> 38.85 / 3
=> 12.95
the cost of each CD is 12.95
