Answer:
$49.18
Step-by-step explanation:
Dinner cost $38.95 before tax and tip are included.
Directions say to ADD 7% tip first so,
38.95 multiplied by 7%= 2.7265, Round up to $2.73
ADD $38.95 and $2.73 tax= $41.68
Now, multiply $41.68 by 18% to find the tip amount
$41.68 * 18%= 7.5024, Round to $7.50
ADD $41.68 and $7.50 to get answer: $49.18
