Question

A problem states: "There are 9 more pencils than pens in a container. There are 25 writing utensils in the container in all. How many pens are there in the container?" Let p represent the number of pens. Which equation represents the situation? p + 9 = 25 2p−9=25 2(p+9)=25 2p + 9 = 25

Answer 1

2p + 9 = 25 is the correct equation

Answer 2

The answer is 2p+9=25. If we solve the equation we see it's true.
2p+9=25
2p=25-9
2p=16
p=16/2
p=8.
Hope this helps.
