Answer:

w: number of weeks

Step-by-step explanation:

Because it mentions she starts with $400 and spends $40 a week. That's like saying every week she'll spend $40.

Just because I feel like it, I'll give you the equation.

40w = 400

400/40 = w

Hope that helps and have a great day!

Answer:

$s\geq 36$

Step-by-step explanation:

Step 1, how many knives to buy?

The restaurant already has 262 knives. 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 we can divide to find the # of packs she needs to buy, determined by variable s.

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

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

$s\geq 36$

I hope this helps! Let me know if you have any questions :)
