In order to find this, we must first find the total amount of the bill. We can do this by multiplying the amount of the check by the tax amount and then by the tip amount.
$63.84 * 7% = $4.47
$63.84 * 20% = $12.77
Now we add the amounts of the tax and tip to the original bill.
$63.84 + $12.77 + $4.47 = $81.08
And to find the total amount for each of the 3 people, divide that bill 3 ways.
