**Question 11**:

Britney rents a stall to sell cakes. The rental of the stall is RM500 per month. The cost for baking a cake is RM5 per box and she sells it at RM10 per box. What is the minimum box of cakes must Britney sell each month to make a profit?

*Rental of the stall = RM500 monthly*

**Solution**:Cost of baking a cake per box = RM5

Selling price per box = RM10

Profit per box

= RM10 – RM5

= RM5

The number of boxes of cakes to accommodate the cost

= RM500 ÷ RM5

= 100

Hence, the minimum box of cakes must Britney sell each month to make a profit = 101
