(a)

Answer to Problem 46SGR
The rent is
Explanation of Solution
Given:
Consider that rent of Movie Theater is $100 plus $30 per hour.
Calculation:
Now, if rent is denoted by y and number of hours is denoted by x
And, we know that the general equation of the line in slope intercept form is
Here, m represents slope of the line that represents change in y with respect to change in x
Hence, number of hours is directly related to rent. It means that if number of hour’s increases then rent also increases.
Thus, the rent is
Conclusion:
Therefore, the rent is
(b)
To find:the cost of renting the theater for 4 hours.
(b)

Answer to Problem 46SGR
The cost of renting is $220.
Explanation of Solution
Calculation:
In order to calculate cost of renting for 4 hours, put the value of
Conclusion:
Therefore, the cost of renting is $220.
