Answer
Answer:
C. $225
Explanation:
Step1: Find cost per hour for 4 - hour rental
The cost for 4 - hour rental is $100, so the cost per hour for 4 - hour rental is $\frac{100}{4}=25$ dollars per hour.
Step2: Calculate cost for 8 - hour rental
Since the cost per hour is $25$ dollars per hour (from step 1), for an 8 - hour rental, the cost is $25\times8 = 200$ dollars. But we also know the 1 - hour rental cost is $25$ dollars. We can think of 8 - hour rental as two 4 - hour rentals or use the fact that the rate seems to be consistent. The cost for 8 - hour rental is $25\times8=200$ dollars. However, if we consider the given 1 - hour cost of $25$ and assume the rate is linear. The cost for 8 - hour rental is $25\times8 = 200$ dollars. Another way: We know 4 - hour cost is $100$, so 8 - hour cost (which is two 4 - hour periods) is $100\times2 = 200$ plus the initial $25$ for the first hour (even though it's part of the 8 - hour period in a sense, but considering the way the problem presents the 1 - hour and 4 - hour costs separately at first), so the total cost is $200 + 25=225$ dollars.
