Lincoln received $55 on his birthday. If he deposits $22 into his bank account, what is the percentage of the total that Lincoln earned?

Zero, the $55 was a gift.

To find the percentage of the total that Lincoln earned, we need to calculate the ratio of the amount Lincoln earned to the total amount.

The total amount Lincoln received on his birthday is $55. After Lincoln deposits $22 into his bank account, the amount he earned is $55 - $22 = $33.

Now, let's calculate the percentage Lincoln earned:

Percentage = (Amount earned / Total amount) * 100

Percentage = ($33 / $55) * 100

Percentage = 0.6 * 100

Percentage = 60%

Therefore, Lincoln earned 60% of the total amount.

To find the percentage of the total that Lincoln earned, we need to compare the amount he received ($55) to the total amount after he deposited $22 into his bank account.

First, calculate the total amount after the deposit:
Total amount = Amount received - Deposit
Total amount = $55 - $22
Total amount = $33

Next, calculate the percentage of the total that Lincoln earned:
Percentage = (Amount received / Total amount) * 100
Percentage = ($55 / $33) * 100
Percentage = 1.6666666666666667 * 100
Percentage ≈ 166.67%

Therefore, Lincoln earned approximately 166.67% of the total amount.
