- How many post-it pads did the shop sell in August?
- The number of post-it pads sold in November was an 80% decrease from the number sold in October. How many post-it pads were sold in November?
(a)
Number of post-it pads sold in August = 40
(b)

20% → 20 x 0.35 = 7
Number of post-it pads sold in November = 7
