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 <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:

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

$s\geq 36$

Chi has $11:30 in dimes and quarters. The number of dimes is three more

Oliga [24]

Answer:

To solve this question, we first have to know that we are trying to assemble

and solve equations with two variables: x

and y.

Assuming x

is the number of dimes and y

is the number of quarters, we

can assemble the equations.

since the number of dimes is 3 more than three times the number of quarters,

we get x=3y+3.

Additionally, multiplying the number of dimes by 0.1 and the number of

quarters by 0.25,

we get the total value of x

and y

which appears by this

equation 0.1x+0.25y=11.30

.

Substituting the value of x

in the second equation, we get 0.1(3y+3)+

0.25y=11.30

.

Solving this equation, we get that the value of x,

we get x=3×20+3=

Using the first equation to get the value of x,

we get x=3×20+3=

60+3=63

dimes.
