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?
 
 Solution:
 
Rental of the stall = RM500 monthly
 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
