13 There are 307 chairs in the cafeteria. Mx. Mildenhall wants to put pads on the
bottom of each of the chair’s four legs so they don’t scratch the floor. Which
equation can be used to determine the number of pads, , Mx. Mildenhall needs?
A
B
C
D

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!
