Candies were sold by mass as shown. Rashid bought a packet of candies which weighed 250 g. How much did he pay? Ans: $ ___

1. Identify the cost of the first 100 g

Cost of first $100\text{ g} = \char36{}5$

2. Calculate the remaining mass to be paid for

Remaining mass $= 250\text{ g} - 100\text{ g} = 150\text{ g}$

3. Calculate the number of additional 50 g blocks

Number of $50\text{ g}$ blocks $= 150 \div 50 = 3$

4. Calculate the cost of the additional mass

Cost of additional mass $= 3 \times \char36{}2 = \char36{}6$

5. Calculate the total cost

Total cost $= \char36{}5 + \char36{}6 = \char36{}11$
