The waiter at El Jarrito brought you the bill. The amount was $53.70. You thought the waiter did the best job you have even seen
grandymaker [24]

Answer:

$64.44

Step-by-step explanation:

To find the amount for the tip, multiply $53.70 by 20%.

First, change 20% to a decimal by moving the decimal left two places, or dividing 20 by 100.

20% = 0.2 as a decimal

Now you can multiply to find the tip.

$53.70 x 0.2 = $10.74

Finally, add the tip to the amount of the bill.

$53.70 + $10.74 = $64.44
