Answer:
2 Hours
Step-by-step explanation:
4/7 of an hour = 34.3 minutes.
34.3 minutes per 2/7
4/7 = 68.6 OR 1 hour 8 minutes.
6/7 = 102.9 OR 1 hour 42 minutes.
Then add half of 34.3 (17.15)
7/7 = 120.05. = 2 hours 0.5 seconds.
I think its 1.012(500 - 100) = 400* 1.012 = 404.80 dollars
All but the last one I think but don't quote me
