Answer:
Steve's pay is the highest and is equal to 55 dollars per hour.
The column for pay corresponding to 1 hour is $55.
Step-by-step explanation:
Geeta's pay:
The equation for Geeta's pay is given as:
Where, 'p' is in dollars and 'h' is in hours.
The above equation is a linear equation of the form , where 'm' is the rate of change of pay or the pay per hour.
So, the pay per hour of Geeta is 45 dollars.
Richard's pay:
The graph of Richard's pay is a straight line. The slope of the line gives the rate of change of pay or the pay per hour.
The slope of the line is given as:
Slope = Rise over run = dollars per hour.
So, Richard's pay per hour is 30 dollars.
Steve's pay:
The table of hours and pay is given.
The rate of change or pay per hour can be obtained by using two values of both hours and pay.
Consider and
Now, pay per hour = dollars
Therefore, Steve's pay per hour is 55 dollars.
The column for pay corresponding to 1 hour is $55.
On comparing, Steve's pay is the highest and is equal to 55 dollars per hour.
