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
How to find the mixed number to a fraction:
Let's take 3/2 for instance.
1) You will see how many times the denominator (bottom number) goes into the numerator (top number) in this case that is one time.
2) You will place that number (1) off to the side like so --> 1
3) Then you will see how many parts are left, in this case that is 1 and place that number over the original denominator like so: 1/2
4) Finally you will just combine to get your answer- 1 1/2
