<PRE><B>Question 299074</B>
The cost, C (in dollars), of renting the office space is given by the function 
C(x) = 0.95x + 350, where x is the number of hours the building has been rented. Answer the following questions, and be sure to show work on the steps for calculating: 
What is the cost to rent the building for 400 hours? 
If the cost of renting the building is $1,000, how many hours was the building rented? 
----
C(x) = 0.95x + 350
C(400) = 0.95(400) + 350
C(400) = $730 (Cost to rent for 400 hours)
-----------------------
1000 = 0.95x + 350
0.95x = 650
x = 681.24 hours (hours it was rented)
