Question

Table.png The table above shows the fees that must be paid to a car rental agency if a rental car is returned late. Hours late is always rounded up to the nearest integer. A customer rented a car for $160.00 and is late returning the car at the appointed drop-off time of 6:00 a.m. Rounded up to the nearest hour, when did he return the car? (1) The late fee for his rental was $40.00. (2) If he had returned the car one hour earlier, he would have paid $24.00 less in late fees.

The table above shows the fees that must be paid to a car rental agency if a rental car is returned late. Hours late is always rounded up to the nearest integer. A customer rented a car for $160.00 and is late returning the car at the appointed drop-off time of 6:00 a.m. Rounded up to the nearest hour, when did he return the car?

IMO C

1)The late fee for his rental was $40.00.

\frac{40}{160}=25%  So he return his car in an interval of 6 - 9 hours later. Not sufficient

2)If he had returned the car one hour earlier, he would have paid $24.00 less in late fees.

\frac{24}{160}=15%  So there is a gap between the intervals of 15%, that gives us 2 options 6 - 9 hours later (10+15=25%) and 10 - 15 hours later (25+15=40%). Not sufficient
 
Now (1)+(2) : given statement 1 we know that he returned his car from 6a.m.+6 hours = 12a.m. to 6a.m.+9 hours = 3p.m. interval =  
Given statement 2 we know that if he had returned the car one hour earlier, he would have paid less. So he must have returned his car at 12am
IMO C

i don't understand how it's C and not D? the question asks us to round to the nearest hour, so isn't it a given that the time range of 6-9 hours late becomes 6 hours late (therefore 6am + 6h = 12pm)? (2) on its own is insufficient, but combined with (1) would make sense since it would let us pinpoint the range better, although even with 'x - 24' for fees, we could discern that '24 = 15% of 160' so x is 25%? that would make both statements individually sufficient, specifically because we are asked to 'round to the nearest hour' in the header
