Consider the Q and A. Q: A 10 m long and 8 m wide rectangular floor is to be covered with a square carpet with 4 m sides. How many square meters of the floor are uncovered?
A: 64
What is the step-by-step reasoning process?
Step-by-step reasoning process: The area of the floor is 10 m x 8 m = 80 square meters. The area of the carpet is 4 m x 4 m = 16 square meters. Therefore, the area of the floor not covered by the carpet is 80 square meters - 16 square meters = 64 square meters,.

Consider the Q and A. Q: Scott has 7 pairs of shoes. Anthony has 3 times as many pairs of shoes as Scott, and Jim has 2 less pairs than Anthony. How many more pairs of shoes does Anthony have compared to Jim?
A: 2

The total number of apples delivered was: 180 apples x 12 crates = 2160 apples. So, the number of remaining apples after throwing away the rotten ones was: 2160 apples – 160 apples = 2000 apples. And now, we can find the total number of boxes of apples by dividing the remaining number of apples by the number of apples per box: 2000 apples / 20 apples / box = 100 boxes of apples.
