Answer: To calculate the tip amount, we need to multiply the bill amount by the percentage tip as a decimal:
Tip amount = 0.20 x $76 = $15.20
To find the total amount to pay, we add the bill amount and the tip amount:
Total amount = $76 + $15.20 = $91.20
Rounding this to the nearest dollar gives:
Total amount = $91
Therefore, you need to pay $91 in total if you leave a 20% tip on a $76 bill.
