PSLE Look at the graph and answer the following questions.
- How many post-it pads did the shop sell in February?
- The number of post-it pads sold in May was an 80% decrease from the number sold in April. How many post-it pads were sold in May?
(a)
Number of post-it pads sold in February = 30
(b)
Total number of post-it pads sold in May as compared to April

20% → 20 x 0.25 = 5
Number of post-it pads sold in May = 5
