[Question]: 50% of substitute teachers walk out after 1 hour of teaching. 30% of the remainder quit before lunch. If 60 substitute teachers show up at 7 AM, how many will be left after lunch?
[Answer]: First find the number of substitute teachers left after half quit: 60 teachers / 2 = 30 teachers. Then find how many teachers quit after an hour but before lunch: 30 teachers * 30% = 9 teachers. Then subtract that number from the number of teachers left after one hour to find how many are left after lunch: 30 teachers - 9 teachers = 21 teachers.
So the answer is 21.

[Question]: Steve is building a bench for the playground and needs 6 lengths of wood that measure 4 feet and 2 lengths of wood that measure 2 feet. How many feet of wood does Steve need to buy?

Steve needs 6 lengths of 4 feet of wood or 6 x 4 = 24 feet of wood. He also needs 2 lengths of 2 feet of wood or 2 x 2 = 4 feet of wood. Altogether, Steve needs 24 feet of wood + 4 feet of wood = 28 feet of wood.
So the answer is 28.
