PSLE Look at the graph and answer the following questions.
- How many staplers did the shop sell in August?
- The number of staplers sold in November was an 20% decrease from the number sold in October. How many staplers were sold in November?
(a)
Number of staplers sold in August = 5
(b)
Total number of staplers sold in November as compared to October
= 100% - 20%
= 80%
100% → 20
1% → 20 ÷ 100 = 0.2
80% → 80 x 0.2 = 16
Number of staplers sold in November = 16
Answer(s): 5; (b) 16
