Answer:
7 lbs. or option B.
Explanation:
To figure out how much the chairs weigh to then divide them, you first need to subtract 36 from 92.
92 - 36 = 56
Now, we have to divide 56 by the number of chairs we have because we need to find out how much a single chair weighs.
56 ÷ 8 = 7
So, each chair weighs 7 lbs.
