Brian places baseball cards in an album with 9 on each page. He could represent the total number of baseball cards he has in an album using the expression 9t.

A. 9 × 16 B. 9 × 7 C. 7t D. 16t

Okay, if this is the expression he would have used before adding 7 more cards to each page, 9t, and then he added 7 more, the expressio would stay the same, the number wouldn't.
