- Calculate the amount spent: Lana spends 80% of $60.80% of 60=0.80×60=4880\% \text{ of } 60 = 0.80 \times 60 = 4880% of 60=0.80×60=48So, she spends $48.
- Determine the remaining amount:60−48=1260 – 48 = 1260−48=12Lana has $12 remaining.
- Calculate the profit earned from the investment: She earns an 80% profit on the remaining $12.80% of 12=0.80×12=9.6080\% \text{ of } 12 = 0.80 \times 12 = 9.6080% of 12=0.80×12=9.60
- Add the profit to the remaining amount:12+9.60=21.6012 + 9.60 = 21.6012+9.60=21.60
Correct answer: A. $21.60
