Final answer:
To calculate the number of hours Howard works in a week, you can use the expression 7(x+1), where x represents the number of hours Ron works per day.
Step-by-step explanation:
To calculate the number of hours Howard works in a week, we need to first determine the number of hours Ron works. Let's assume Ron works x hours per day. Since Howard works one more hour each day than Ron, Howard works (x+1) hours per day.
Since there are 7 days in a week, Ron works a total of 7x hours in a week and Howard works a total of 7(x+1) hours in a week.
Therefore, the expression to calculate the number of hours Howard works in a week is 7(x+1).
