|x| is tricky but maybe I can tell you so that it's clear 4ever.
You have to look at when what's inside the absolute value iszero. In this case x=0. That easy. Then, you have to split the cases:
For x>= 0, you have y = -x+1,
For x<=0, you have y = -(-x) + 1 = x+1, because abs(x)=-x, if x<=0.
Notice that x=0 is included in either case, because |x| is continuous.
Then plot each line choosing a couple of points, notice that for one case you should choose x=-1, -2, or x=0, but not positive values, and the other way for the case with x>=0.

The whole number part is written first
here it is 16
The decimal part starts with tenths, hundredths and so on
here we have .897
so we have 8 tenths, 9 hundredths and 7 thousandths
combinedly they are written as
Sixteen and eight hundred and ninety seven thousandths
What I would do is start with the price of the dessert and the sales tax $3.85+ $1.15= $5. I started with this because when you add the cents they equal a dollar which makes it easier to continue.
Then I would add the 2.75. This would be 7.75.
Then add 7.75 + 8.50. To simplify this, you can add 7 + 8, then .75+ .50
Which would equal 15 + 1.25 + 16.25
You have to find the cube root of 27.
A same number when multiplied 3 times by itself will give the cube.
3√27 = 3 x 3 x 3
So the answer is 3
