Question: Mama bird has 6 babies in the nest. She needs to feed each baby 3 worms a day. Papa bird caught 9 worms. If she caught 13 worms and had 2 stolen, how many more does she need to catch to feed them for 3 days? Think carefully first, then make a decision:
Each day, mama bird needs to catch 6 x 3 = 18 worms. For 3 days, she needs 18 x 3 = 54 worms. She already has 13 - 2 = 11 worms. With papa bird’s catch, they have 11 + 9 = 20 worms. To feed the babies for 3 days, she needs to catch 54 - 20 = 34 more worms. So the answer is 34.
