- How many correction tapes did the shop sell in March?
- The number of correction tapes sold in May was an 80% increase from the number sold in April. How many correction tapes were sold in May?
(a)
Number of correction tapes sold in March = 30
(b)

180% → 180 x 0.4 = 72
Number of correction tapes sold in May = 72
