  • Q #3: Lana has $60. She spends 80% of the money. She then invests the remaining amount and earns a profit of 80%. How much money does she now have?

    A. $21.60

    B. $86.40

    C. $9.60

    D. $60

    Answer Explanation

    we are needed to find the amount Lana is left with after spending and investing the rest using the given information.

    Amount Lana spends = 80% of $60= 80/100 * 60 = $48

    Amount left to invest = $(60-48) = $12

    Lana is left with $12, which she invests and earns a profit of 80%.

    Profit earned = 80% of $12 = 80/100 * 12 = $9.20

    So, Lana will have $12 + $9.20 = $21.60
