The correct answer is option B, $343.36
I came to the conclusion by multiplying the rental cost by the tax rate= 9.36 and then multiplying the daily insurance fee by the amount of days- 20*5=100 and then adding 234+9.36+100 which equals 343.36. The general formula for finding the total cost would be Rental charge+ +(rental)(tax rate)+(Insurance)(# of days)
Hope this helps a bit
