Reasoning and answer: The price per egg in a tray is $12 / 30 eggs = $0.4 / egg. The equivalent of $0.4 in cents is $0.4 x 100 cents / dollar = 40 cents. Hence, you can save 50 cents - 40 cents = 10 cents per egg if you buy a tray.
The answer: 10

Reasoning and answer: 3 foxes catch 4 weasels each every week for a total of 3 * 4 = 12 weasels. 12 weasels are caught every week for 3 weeks for a total of 12 * 3 = 36 weasels. 3 foxes catch 2 rabbits each every week for a total of 3 * 2 = 6 rabbits. 6 rabbits are caught every week for 3 weeks for a total of 6 * 3 = 18 rabbits. There were originally 100 weasels so now there are 100 - 36 = 64 weasels left. There were originally 50 rabbits so now there are 50 - 18 = 32 rabbits left. There are 64 + 32 = 96 weasels and rabbits left.
The answer: 96
