Answer: 162% of original price was paid by Stanley for the bike.
Step-by-step explanation:
let the original price paid by Sam be x
Then Sam sold his bike to Suzie for 35% more than he paid for it.
Price paid by Suzie = x + 35% of x = x + 0.35 × x = 1.35 x
After which Suzie then sold the bike to Stanley for 20% more than what she paid for it.
Price paid by Stanley = 1.35 x + 20% of 1.35x = 1.35 x + (0.20) × 1.35x = 1.62x
Percent of the original price paid by Stanley for bike
Hence,162% of original price was paid by Stanley for the bike.
