Therese bought 10 bags of buai at K400 each. She paid K2 000 for vehicle hire, and spent K1 000 on other expenses. She sold 8 bags at K900 each and 2 bags at K700 each. What would be her profit or...?

To calculate Therese's profit or loss, we need to first calculate her total expenses and total revenue.

Total expenses:
Cost of 10 bags of buai = 10 bags x K400 = K4,000
Vehicle hire = K2,000
Other expenses = K1,000
Total expenses = K4,000 + K2,000 + K1,000 = K7,000

Total revenue:
Revenue from selling 8 bags at K900 each = 8 bags x K900 = K7,200
Revenue from selling 2 bags at K700 each = 2 bags x K700 = K1,400
Total revenue = K7,200 + K1,400 = K8,600

Profit or loss:
Profit = Total revenue - Total expenses
Profit = K8,600 - K7,000
Profit = K1,600

Therese's profit from selling the buai would be K1,600.

Calculating Total Costs:

- Buai cost: 10 bags x K400/bag = K4,000
- Vehicle hire: K2,000
- Other expenses: K1,000
- Total cost: K4,000 + K2,000 + K1,000 = K7,000

Calculating Sales Revenue:

- 8 bags sold at K900/bag: 8 x K900 = K7,200
- 2 bags sold at K700/bag: 2 x K700 = K1,400
- Total sales revenue: K7,200 + K1,400 = K8,600

Calculating Profit or Loss:

- Profit = Sales revenue - Total costs
- Profit = K8,600 - K7,000
- Profit = K1,600

Therefore, Therese made a profit of K1,600 after deducting all her costs and expenses.
