There was a competition that attracted 630 entries for a $250 prize. Molly gets paid $7.50 per hour for checking the entries, which takes her 2 minutes each. How much do they pay Molly to check the entries?
(1/30)hour/entry * 630 entries = 21 hours
21 hours * $7.50/hour = $157.50
They are not paying her enough.
