HELP!

Any type of explanation would be greatly appreciated! :)

Vaughn collected 72 pieces of litter.

Step-by-step explanation: The equation is correct. You get that by going backwards through the information in the story.

Vaughn's number is x.

Piper is 1/4 x

Sara is Piper +12 So (1/4 x)+12

Dom is Sara -15. So (1/4 x) -3

Add all Piper, Sara & Dom on one side of the equation.

The other side is the Vaughn's amount minus 9 because it says he picked up 9 more than the others combined. So x-9 equals the amount of the other three combined.

The three 1/4 x add to 3/4 x

Skipping to the solution:

x - 3/4 = 12 -3 +9

1/4 x = 18 Multiply both sides by 4

x = 72

1/4 x is 18, Piper's number.

Use that to calculate the Sara and Dominique.
