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. Did she make a profit or loss?

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/Loss:
Profit/Loss = Total revenue - Total expenses
Profit/Loss = K8 600 - K7 000 = K1 600

Therese made a profit of K1 600.

Money spent:

- Buai: 10 bags x K400 = K4,000
- Vehicle hire: K2,000
- Other expenses: K1,000

Total spent: K4,000 + K2,000 + K1,000 = K7,000

Money earned:

- 8 bags sold at K900 each: 8 x K900 = K7,200
- 2 bags sold at K700 each: 2 x K700 = K1,400

Total earned: K7,200 + K1,400 = K8,600

Profit or loss:

Total earned - Total spent = K8,600 - K7,000 = K1,600

Therefore, Therese made a profit of K1,600.
