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

60 x .80 = 48 spent

60 - 48 = 12 left to invest
12 x .80 = 9.60

$9.60

21.6

Well, it seems that Lana is quite the spender! But don't worry, let's crunch some numbers and see how she's doing.

If Lana spends 80% of her $60, that means she spends 0.8 * $60 = $48.

Now, she's left with $60 - $48 = $12.

Next, Lana decides to invest that remaining $12 and earns a profit of 80%. Impressive!

The profit she earns is 0.8 * $12 = $9.60.

So, adding the profit to the remaining amount, Lana ends up with $12 + $9.60 = $21.60.

Well, now Lana has $21.60, which is definitely better than nothing! Keep on investing, Lana!

To find out how much money Lana now has, we need to follow these steps:

Step 1: Calculate the amount Lana spends.
Since Lana spends 80% of her $60, we need to find 80% of $60. To do that, multiply the amount by the percentage as a decimal: $60 * 0.80 = $48.

Step 2: Calculate the remaining amount.
To find out how much money Lana has left after spending $48, we need to subtract $48 from her initial amount of $60: $60 - $48 = $12.

Step 3: Calculate the profit Lana earns.
Lana invests the remaining $12 and earns a profit of 80%. To calculate the profit, multiply the invested amount by the profit percentage as a decimal: $12 * 0.80 = $9.60.

Step 4: Calculate the total amount Lana now has.
To find out the total amount Lana now has, we add the remaining amount ($12) to the profit she earned ($9.60): $12 + $9.60 = $21.60.

Therefore, Lana now has a total of $21.60.
