Answer:
On May 1st, the final price was approximately 40.96% of the original price of A.
Step-by-step explanation:
Price A: 100 (The original 100 %)
End of January: 100 + (100*60%) = 100 + 60 = 160
End of February: 160 – (160*60%) = 160 - 96 = 64
End of March: 64 + (64*60%) = 64 + 38.4 = 102.4
End of April: 102.4 – (102.4*60%) = 102.4 - 61.44 = 40.96
