Answer:
First part: 10.035
Second part: 10.40
Third part: 65.785 or 65.80
( going by how you listed the problem )
Explanation:
First we would need to find out:
What is 18% of 55.75?
Which equals: 10.035
That is only step one of our problem ( there are three steps ) next we need to find out what is the total amount + the tip
Do simple math for the answer,
55.75 + 10.035 =
65.785
Last we need to use 10.035 and round it to the nearest hundreth which the following shows:
35 < 40
10.40.
Thus the answer to your problem is, 10.40, 65.785, and 10.035
