A. [tex]$150[/tex]
B. [tex]$200[/tex]
C. [tex]$225[/tex]
D. [tex]$250[/tex]

Answer :

To find out how much it will cost Susan to rent a truck for her entire 8-hour workday, let's break it down step by step:

1. Understand the Cost per Hour:
- Susan paid [tex]$25 to rent the truck for 1 hour.
- She also paid $[/tex]100 to rent the truck for 4 hours. The cost for these 4 hours can be checked as [tex]$25 per hour (since $[/tex]100 ÷ 4 hours = [tex]$25 per hour).

2. Calculate the Total Cost for 8 Hours:
- If it costs $[/tex]25 per hour, you can multiply the hourly rate by the total number of hours Susan needs the truck. So, for an 8-hour day, the cost will be:
[tex]\[
25 \text{ dollars/hour} \times 8 \text{ hours} = 200 \text{ dollars}
\][/tex]

Therefore, the cost for Susan to rent the truck for 8 hours is [tex]$200. The correct choice is B. $[/tex]200.
