To find out how many extra chairs will be stored, we first need to calculate the total number of chairs from both orders:
- First order: 180 chairs
- Second order: 204 chairs
Total chairs = 180 + 204 = 384 chairs
Next, we need to determine how many chairs will go into each of the 17 classrooms. We do this by dividing the total number of chairs by the number of classrooms:
Chairs per classroom = Total chairs ÷ Number of classrooms
Chairs per classroom = 384 ÷ 17
Now we perform the division:
384 ÷ 17 = 22.588...
Since we can't have a fraction of a chair, we take the whole number part, which is 22. This means each classroom will receive 22 chairs.
Now we calculate how many chairs will be distributed in total:
Chairs distributed = 22 chairs/classroom × 17 classrooms = 374 chairs
Finally, to find out how many chairs will be put into storage, we subtract the number of distributed chairs from the total number of chairs:
Extra chairs = Total chairs - Chairs distributed
Extra chairs = 384 - 374 = 10 chairs
Thus, the number of chairs that will be put in storage as extra chairs is 10.
The correct answer is A) 10.
