B-first · Complete sign packs · exact four-response paper

This paper repeats the exact held source and four questions. It is different from ordinary seven-heading Desk paper.

Fifteen whole sign cards are available. Every complete pretend sign pack needs three cards.

How many complete packs can be made?

Show every one of the 15 sign cards in a model with exactly 3 in each complete group.

A pretend helper suggests: “Three.” Does that name the correct number of complete groups? Explain.

Show a check using the complete-group rule and the whole original collection.
