Niu has decorated x cards. He started with 24 stickers, and he used 4 stickers per card. Which expressions can we use to describ
Kisachek [45]

Answer:

24-4x

Step-by-step explanation:

We have been given that Niu has decorated x cards. He started with 24 stickers and he used 4 stickers per card. So stickers used in x cards will be 4x.

As initial number of stickers was 24, so we can find number of stickers left after decorating x cards by subtracting number of stickers used in x cards from 24.

\text{Number of stickers that Niu has left}=24-4x

Therefore, the expression 24-4x will represent the number of stickers that Niu has left after decorating x cards.
