1. The problem involves calculating the monthly balance (Saldo) by subtracting total expenses (Udgifter) from total income (Indtægter) for each month. 2. The formula for the balance is: $$\text{Saldo} = \text{Indtægter} - \text{Udgifter}$$ 3. First, calculate total income and total expenses for each month: - Indtægter (Income) = Løn + Lommepenge - Udgifter (Expenses) = Tøj + Mobil + Transport + Mad og slik + Biograf m.m. 4. Calculate for January: - Indtægter = 1275 + 200 = 1475 - Udgifter = 250 + 75 + 150 + 40 + 60 = 575 - Saldo = 1475 - 575 = 900 5. Calculate for February: - Indtægter = 800 + 200 = 1000 - Udgifter = 300 + 75 + 150 + 25 + 110 = 660 - Saldo = 1000 - 660 = 340 6. Calculate for March: - Indtægter = 975 + 200 = 1175 - Udgifter = 280 + 75 + 150 + 80 + 95 = 680 - Saldo = 1175 - 680 = 495 7. Calculate for April: - Indtægter = 895 + 200 = 1095 - Udgifter = 200 + 75 + 150 + 65 + 80 = 570 - Saldo = 1095 - 570 = 525 8. Calculate for May: - Indtægter = 1050 + 200 = 1250 - Udgifter = 345 + 75 + 150 + 20 + 125 = 715 - Saldo = 1250 - 715 = 535 9. Calculate for June: - Indtægter = 945 + 200 = 1145 - Udgifter = 120 + 75 + 150 + 35 + 75 = 455 - Saldo = 1145 - 455 = 690 Final balances (Saldo) for each month are: - January: 900 - February: 340 - March: 495 - April: 525 - May: 535 - June: 690 This shows how much money remains after expenses each month.
