Homer the Hungry Hippo is munching on the lily pads in his pond. When he got to the pond, there were 30 lily pads, but he is eat
ing 5 lily pads an hour. Henrietta the Hungrier Hippo found a better pond with 38 lily pads! She eats 7 lily pads every hour. If Homer and Henrietta start eating at the same time, when will their ponds have the same number of lily pads remaining?
How many lily pads will be left in each pond at that time?
