Answer: C) 25

Step-by-step explanation:

x²+10x+ __=16+ __

Answer:

s\geq 36

Step-by-step explanation:

Step 1, how many knives to buy?

The restaurant <u>already has 262 knives</u>. We can subtract this number from their needed 694 knives to find how many they still need:

694-262=432 knives.

Step 2, how many sets of knives?

The restaurant needs to buy 432 knives. We know the knives come in sets of 12, so <u>we can divide to find the # of packs she needs to buy</u>, determined by variable <em>s</em>.

Notice how the restaurant needs to buy a minimum of 694 knives, hence we use a greater or equal than symbol:

\fbox{\frac{432}{12} \geq s}\\s\geq \frac{432}{12}

s\geq 36

<em>I hope this helps! Let me know if you have any questions :)</em>
