Question is not written properly but i think you are looking for the table of given equation y=400-55x. So I will explain about how to get that.
number of hours can't be negative so that means x must be 0 or more.
like x=0,1,2,3,...
we just have to plug these x-values into above equation to find the y-value in order to calculate table.
I will show you calculation for x=2
y=400-55x=400-55*2=400-110=290
so the point in table will be (2,290)
similarly we can find more point and get final table as shown below:

Answer:
see below
Step-by-step explanation:
If your calculator doesn't have a % key, you can change each of the percentages to a decimal by dividing the numerical value by 100. "%" means "/100".
44% = 44/100 = 0.44 . . . . . . both fractions are read "forty-four hundredths"
Then 44% of 205 = 0.44×205 = 90.2
When you have repetitive calculations like this, a spreadsheet or calculator is handy.
