Abdul's bill at a restaurant is $28.65. He wants to leave and 18% tip for the waiter. What is the total amount Abdul should leave? Round to the nearest cent.

$5.16
$33.81
$23.49
$29.44

To find the total amount Abdul should leave, he needs to add the bill amount ($28.65) to the tip amount.

The tip amount is calculated by multiplying the bill amount by the tip percentage (18% = 0.18).
So, the tip amount is $28.65 * 0.18 = $5.17 (rounded to the nearest cent).

Adding the bill amount and the tip amount, the total amount Abdul should leave is $28.65 + $5.17 = $33.82 (rounded to the nearest cent).

Therefore, the correct answer is $33.81.
