A box of markers costs $4. Mr. Reed spent $92 on markers. The number of boxes, b, can be found by solving the equation 4b=92.

Answer: the answer is 23

Step-by-step explanation: since you are trying to find the number of boxes, b, the first thing you do is isolate it by dividing 4b by 4 this eliminates the 4, and because you did it on one side you have to do it on the other so you work would look like this 4b/4=92/4 you equation would look like this when done b=23
