Passage / Scenario
After spending 80% of her $60, Lana is left with how much money when she invests the remaining amount and earns an 80% profit?
Correct answer
A
Rationale
After spending 80% of $60, Lana spends $48, leaving her with $12. When she invests this remaining amount and earns an 80% profit on $12, it amounts to $21.60 ($12 + 80% of $12 = $12 + $9.60 = $21.60). Therefore, Lana now has $21.60 in total.
