Answer:
Part (A): The scale of y: 1 interval being equal to 500 units and from 14,000 to 18,500.
Part (B): The good interval to use for the y-axis should be 1 to 10.
Step-by-step explanation:
Consider the provided information.
As we know the X axis represents the independent variable, since years are the independent variable. So, X axis represents the years.
Y axis represents the dependent variable, since average cost is dependent variable. So, Y axis represents the average cost.
Part (A) what is a good scale to use for the y-axis?
It is given that range is from $14,000 to $18,500.
So, 1 interval being equal to 500 units, so that it will suitable for 18,500.
The scale of y should be 14,000 to 18,500 as 14,000 is the starting average cost and 18,500 is the last average cost.
Part (b) what is a good interval to use for the y-axis?
The scale for x should be 1 year. As It should start from 1 to 10.
The good interval to use for the y-axis should be 1 to 10.
The required scale is shown in figure,
We have been given that Marcus works for 26 hours each week and 48 weeks each year.
Thus in a year he works for hours.
Now, we have been given that Marcus earns $8.40 per hour.
Therefore, in 1248 hours, he earns
Marcus has to pay tax if he earns more than $10,000. Now we have calculated that he earns $ 10483.2 which is higher than $10,000.
Therefore, Marcus has to to pat tax.
