F. None of the above.

Answer 1

The correct expressions to represent the number of stickers Niu has left after decorating 1 card, beginning with 24 stickers and using 4 per card, are '24 - 4' and '4(6)'. The other options do not apply to the situation given.

Step-by-step explanation:

To determine the expressions that describe how many stickers Niu has left after decorating cards, we start from the initial number of stickers and subtract the number of stickers used. Niu started with 24 stickers and used 4 stickers per card. For one card, the calculation is simply the initial number minus four times the number of cards decorated.

The correct expressions to calculate the stickers remaining after decorating 1 card are:

• E. 24 - 4: This shows the initial number of stickers minus the number used for one card.
• C. 4(6): This shows the total number of stickers used for decorating cards since 4 stickers are used per card and Niu has decorated 1 card.
