- How many correction tapes did the shop sell in March?
- The number of correction tapes sold in May was an 40% increase from the number sold in April. How many correction tapes were sold in May?
(a)
Number of correction tapes sold in March = 10

140% → 140 x 0.45 = 63
Number of correction tapes sold in May = 63
