Molly is selling candy bars for a fundraiser. She started at 12:00 p.m. with 60 bars and ended at 5:00 p.m. with 20. How many bars did Molly sell per hour?
Molly sold 60 - 20 = <<60-20=40>>40 candy bars.
Molly sold the candy bars over 5 - 12 = <<5-12=-7>>-7 hours.
Molly sold 40 / -7 = <<40/-7=-5.714285714285714>>-5.71 bars per hour. Answer: \boxed{-5.71}.
Molly is selling candy bars for a fundraiser. She started at 12:00 p.m. with 60 bars and ended at 5:00 p.m. with 20. How many bars did Molly sell per hour?
To find how many bars Molly sold per hour, we need to find the total number of bars she sold and divide it by the total number of hours.
From 12:00 p.m. to 5:00 p.m., there are 5 hours.
Molly started with 60 bars and ended with 20 bars, so she sold 60 - 20 = 40 bars.
Therefore, Molly sold 40 bars / 5 hours = <<40/5=8>>8 bars per hour. Answer: \boxed{8}.
