Answer:
Cost of a bag of chips is $0.75
Cost of a cheeseburger is $3.
Explanation:
[Step 1] Let the cost of a cheeseburger be x.
[Step 2] Let the cost of a bag of chips be y
[Step 3] As it is given that x + y = 3.75
[Step 4] It is also given that 2x + 3y = 8.25
[Step 5] Multiplying the equation in [Step 3] by 2 and we get 2x + 2y = 7.50
[Step 6] Subtracting the equation in [Step 5] from the equation in [Step 4] we get y = $0.75
[Step 7] Therefore the cost of a bag of chips is $0.75
[Step 8] Substituting the value of y found in [Step 7] into [Step 8] we get x = 3.
[Step 9] Therefore the cost of a cheeseburger is $3.
Check Answer:
Chip = 0.75
Cheeseburger = 3.00
Nathan Ordered one cheeseburger and one bag of chips for $3.75.
3.00 + 0.75 = $3.75
Hence, Chip = 0.75 and Cheeseburger = 3.00 is correct.

Jack Ordered two cheeseburger and three bags of chips for $8.25.
2 Cheeseburger = 3.00x2 = 6.00
3 bags of chips = 0.75x3= 2.25
6.00+2.25=$8.25
Hence, Chip = 0.75 and Cheeseburger = 3.00 is correct.
