Answer:

A) 6x + 5y = 82

B) 2x + 5y = 54 We'll multiply equation B) by -1

B) -2x -5y = -54 Then we'll add this to A)

A) 6x + 5y = 82

4x = 28

x = 7

y = 8

Assume that MTA Sandwiches sells sandwiches for $2.85 each. The cost of each sandwich follows:

mixas84 [53]

Answer:

a. profit is lower

b. lowest price $2.29

Step-by-step explanation:

a. We have to analyze how this especial order affect the profit of the company

Profit = Revenue- Total cost = P(x) =(Px * Q)-(FC + vc*Q)

Regular production profit= $2.85 x 18,400 units -$2.60 x 18,400 units=

Regular production profit=4600

Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q)

P2= price of special order

Q2= quantity of special order

Q= Q1 +Q2

Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q)= $2.85 x 18,400 units +$1.85 x 800 units - $18,400- $1.60 x 19600=

Production with special order= 51888 +1480- $18,400- 30720

Production with special order= 4.248‬

b.Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q) =4600

=51888 +(P2 * 800)- $18,400- 30720 =4600

=(P2 * 800)= 4600- 51888 + $18,400+30720

P2=1.832/800 = 2,29

Work the following problem

neonofarm [45]

Answer:

Option B is the correct answer.

Step-by-step explanation:

Given

List Price=$720

The percentage of discount=13%

In order to find the amount of discount, 13% of the amount has to be calculated. To calculate 13% , the amount is multiplied by 13/100.

Amount of discount=13% of list price

=720*13/100

=720*0.13

=$93.60

The amount of discount is $93.6..

A sealed rectangular container 10 inches by 12 inches by 6 inches is sitting on its largest face. If it is filled with water up

Sedaia [141]

Answer:

8 inches

Step-by-step explanation:

Given: Dimension of rectangular container= $(10\times12\times 6)\ inches$

Water is filled up to a level 2 inches from the top.

As given that container is sitting on its largest face, then it is standing on $(10\times 12)\ inches$

Which means the height of container is 6 inches and it ie filled with water up to 2 inches from the top.

∴ Height of water inside the container= $6-2= 4 \ inches$

Now, finding the volume of water inside.

we know, Volume= $length\times width\times height$

Volume= $10\times 12\times 4= 480\ inches^{3}$

Next, if container is placed in its smallest face then it is standing on $(10\times 6)\ inches$ and lets assume height to be "x"

Forming an equation now to express the volume conservation law.

⇒ $480\ inches^{3} = 10\times 6\times x$

⇒ $480= 60x$

dividing both side by 60

⇒ $x= \frac{480}{60}$

∴ x= 8 inches

Hence, 8 inches from the bottom will the water level reach if the container is placed on its smallest face

Given parallelogram SNOW, diagonals SO and NW intersect at D.

Reil [10]

Answer:

The length of SO is 46 units

Step-by-step explanation:

In a parallelogram, diagonals bisect each other, which means meet each other in their mid-point

∵ SNOW is a parallelogram

∵ SO and NW are diagonals

∵ SO ∩ NW at point D

→ That means D is the mid-point of SO and NW

∴ D is the mid-point of SO and NW

∵ D is the mid-point of SO

→ That means D divide SO into two equal parts SD and DO

∴ SD = DO

∵ SD = 9x + 5

∵ DO = 13x - 3

→ Equate them

∴ 13x - 3 = 9x + 5

→ Subtract 9x from both sides

∵ 13x - 9x - 3 = 9x - 9x + 5

∴ 4x - 3 = 5

→ Add 3 to both sides

∵ 4x - 3 + 3 = 5 + 3

∴ 4x = 8

→ Divide both sides by 4

∴ x = 2

→ To find the length of SO substitute the value os x in SD and DO

∵ SO = SD + DO

∵ SD = 9(2) + 5 = 18 + 5 = 23

∵ DO = 13(2) - 3 = 26 - 3 = 23

∴ SO = 23 + 23 = 46

∴ The length of SO is 46 units
