Answer:
Transaction 2: 70.00
Transaction 3: -5.00
Transaction 4: 32.50
Explanation:
For transaction 2, we can use the equation 250 + x = 320 to find the answer
x = 70
For transaction 3, we can use the equation 350 - 325 = y to find the answer
y = -5
For transaction 4, we can use the equation -5 + 37.5 = z to find the answer
z = 32.5
Final answer is as follows:
Transaction 2: 70.00
Transaction 3: -5.00
Transaction 4: 32.50
