The correct equation is .

Solución

To determine the number of pads that Mx. Mildenhall needs for the chairs, we need to consider the following:
  1. There are 307 chairs.
  2. Each chair has 4 legs.
  3. Therefore, the total number of pads needed is equal to the number of chairs multiplied by the number of legs per chair.
Now, let’s analyze the options provided:
A.
  • This suggests that the number of pads is the total number of chairs divided by the number of legs per chair, which is incorrect.
B.
  • This suggests that the number of pads is the sum of the number of legs and the number of chairs, which is also incorrect.
C.
  • This correctly states that the number of pads is the total number of chairs multiplied by the number of legs per chair. This is a valid equation.
D.
  • This suggests that if you multiply the number of pads by the number of legs, you get the number of chairs, which is incorrect.
The correct equation to determine the number of pads needed is:
C.
Thus, Mx. Mildenhall needs pads in total.

To determine the number of pads Mx. Mildenhall needs, you would need to multiply the number of chairs (307) by the number of pads per chair (4). This gives you a total of pads required for all the chairs. Therefore, the correct equation is .
Mistakes are easy to make when setting up equations. One common error would be thinking that you should divide 307 by 4, which would suggest a smaller number of pads used per chair! Remember, when each chair requires multiple pads, multiplication is the way to go!
