Billy and Ann both have a pencil box.
Ann has five times as many pencils in her box as Billy
Ann gives Billy 76 of her pencils so now they have the same number of pencils

Q: How many pencils did Billy have at the end?

"Assuming" one "lot" is seventy-six, I think we're all good here.

114. Ann started out with 190 and Bill started out with 38. Pretty big pencil boxes.

I don't claim to be smarter than a fifth-grader, but boiling it down to 5X=Y-76, it's a trick...

EDIT: Oops. 5X+76...

Would it not also work with Billy with an empty box, as in: 5*0 and Ann with 152?

EDIT: "Ann has five times as many pencils in her box as Billy"

Not if Ann originally had five times as many as Billy.

So did Bob. Did you get the same?
Yep, but not until after I went down the same rabbit hole Doc did! (Great minds and all that, you understand... 😜 )
