Question: There are 50 oysters on the rocks at La Push Park and 72 crabs by the beach. Eric, who loves walking by the beach, makes a note of this and goes home. The next day, he realizes only half the number of Oysters were on the rocks, and only 2/3 the number of crabs as the previous day are on the beach. How many oysters and crabs did he count in total in the two days? Think carefully first, then make a decision:
The first day he saw 50 oysters + 72 crabs = 122 animals. On the second day, he saw 1 / 2 * 50 oysters = 25 oysters. The number of crabs by the beach on the second day was 2 / 3 * 72 crabs = 48. He saw 48 crabs + 25 oysters = 73 animals on the second day. The total for the two days is 73 animals + 122 animals = 195 animals. So the answer is 195.
