Savannah needs to order some new supplies for the restaurant where she works. The

olga2289 [7]

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 :)

What is the domain and range?

MrRissso [65]

Hello from MrBillDoesMath!

Answer:

Domain = { 5. 10. 15. 20}

Range = -3,-1,1,3} .

Discussion:

The domain is the set of all "x" values, that is { 5. 10. 15. 20} and the range is (-3,-1,1,3} . The arrows in the diagram show the mapping between the domain and the range. For examples, 5 -> 1 ( "x value 5 is mapped to y value 1"), 10 ->3, 15 ->-3, and 20 -> -2

Thank you,

MrB
