Question: Boston had .5 feet of snow on the first day of winter. The next day they got an additional 8 inches. Over the next 2 days, 2 inches of the snow melted. On the fifth day, they received another 2 times the amount of snow they received on the first day. How many feet of snow do they now have?
Answer with step-by-step thinking: 12 inches is 1 foot and they received a .5 foot of snow on the first day so they received 12 * .5 = 6 inches of snow. The first day they had 6 inches and then received another 8 inches for a total of 6 + 8 = 14 inches. 2 inches melted from their 14 inches so that leaves 14 - 2 = 12 inches of snow. They received 2 times the amount as the first day's 6 inches of snow so that's 2 * 6 = 12 inches of snow. So they had 12 inches of snow and received another 12 inches of snow for a total of 12 + 12 = 24 inches. 12 inches is 1 foot and they have 24 inches of snow so they have 24 / 12 = 2 feet of snow.
So the answer is 2.


Question: A boy squirrel gathers 6 walnuts and carries them to his burrow in the tree, adding to the 12 already there, and dropping 1 on the way. The girl squirrel brings 5 more walnuts to their burrow and eats 2. How many walnuts are left?
Answer with step-by-step thinking: With the boy’s contribution, there are 12 + 6 = 18 walnuts. When he drops 1, now they have 18 - 1 = 17 walnuts. The girl adds to their stash, making the count 17 + 5 = 22 walnuts. When the girl eats 2, the final count is 22 - 2 = 20 walnuts.
So the answer is 20.


Question: A class has 60 students. The number of students who bring their lunch is thrice the number of those who eat in the school cafeteria. The rest of the students don't eat lunch. If 10 students eat in the school cafeteria, how many don't eat lunch?
Answer with step-by-step thinking:
Multiplying the number of students eating at the cafeteria by three means that 3 * 10 = 30 students bring lunch. The total number of students that eat lunch is 10 + 30 = 40 students. Since the class has 60 students, those who don't eat lunch are 60 - 40 = 20 students.
So the answer is 20.
