After spending 80% of her $60, Lana is left with how much money when she invests the remaining amount and earns an 80% profit?

Rationale

Lana is left with $21.60.

After spending 80% of her $60, Lana is left with $12. When she invests this remaining amount and earns an 80% profit, she makes an additional $9.60 ($12*0.8), which when added to the remaining $12, gives a total of $21.60.

A ($21.60) CORRECT

This is the correct answer. Lana spends 80% of her $60, leaving her with $12. When she invests this remaining amount and earns an 80% profit, she makes an additional $9.60 ($12*0.8). So, her total money after the investment is $12 + $9.60 = $21.60.

B ($9.60) YOUR ANSWER

This option only considers the profit that Lana earns from her investment and does not include the initial investment amount that she had left after spending 80% of her $60.

C ($86.40) YOUR ANSWER

This amount is incorrect as it exceeds Lana's initial amount of $60. After spending 80% of her $60, Lana is left with $12. When she invests this remaining amount and earns an 80% profit, she makes an additional $9.60, not $86.40.

D ($60.00) YOUR ANSWER

This option inaccurately suggests that Lana neither spent any of her money nor made any profit from her investment, which contradicts the information provided in the question.

Conclusion

Lana initially had $60. After spending 80% of this, she was left with $12. She then invested this amount and made an 80% profit, which resulted in an additional $9.60. Therefore, the total amount she had after investing and making a profit was $21.60.

After spending 80% of her $60, Lana is left with how much money when she invests the remaining amount and earns an 80% profit?

Lana is left with $21.60.
