The school has to sell each box for $40 to make a profit of $10 per box because each box costs $30.
There are 50 candy bars per box.
$40/50=$0.80 per candy bar
It's costing the school $30/50=$0.60 per candy bar to buy.
The school sells each candy bar for $0.80, making a profit of $0.20 per candy bar.

Step-by-step explanation:

To isolate n you need to subtract 15 from both sides giving you

2n=72

Then to further isolate n you need to divide 2 from both sides giving you the answer

The solution to the system of equations is

Answers

Answer:

The equation representing the left table is:  

y = 1.5x – 6

The equation representing the right table is:  

y = –4x + 6.1

The solution to the system of equations is:  

(2.2, –2.7)

Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The first table is

x            y

0           -6

1            -4.5

2            -3

3             -1.5

Slope = -4.5+6/1

=1.5

Now let us find y intercept

-6=1.5(0)+b

-6=b

So the equation representing the left table is y=1.5x-6

Now let us find second table

x            y

0           6.1

1             2.1

2           -1.9

3            -5.9

m=2.1-6.1/1=-4

Now y intercept

2.1=-4+b

b=2.1+4

b=6.1

Equation representing the right table is y=-4x+6.1

Now equate two equations

1.5x-6=-4x+6.1

1.5x+4x=6.1+6

5.5x=12.1

x=12.1/5.5

x=2.2

and y=-4(2.2)+6.1

y=-8.8+6.1

y=-2.7

Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

Answers

Answer and Step-by-step explanation:

We are given:

[tex]\frac{2y-1}{-3} = 5[/tex]

First, we multiply both sides by -3.

2y - 1 = 15

Now we add 1 to both sides.

2y = 16

Finally, we divide by 2 to each side.

y = 8

We are given:

2x + 30 = -4(5x -2)

First we distribute the -4 to 5x and -2.

2x + 30 = -20x + 8

Now we subtract 8 from both sides.

2x + 22 = -20x

Now we subtract 2x from both sides.

22 = -22x

Finally, we divide by -22 to both sides.

-1 = x

A 10 33
B 20 ?

Part A
Using Plan B, how many days will it take Morgan to finish her book? Enter your answer in the box.

days

Part B
Which explains how to find the number of days it will take Morgan to finish her book using Plan B?
Select all that apply.
A.


Multiply 20 × 16 to get 320, which is not enough days. So multiply 20 × 17 to get 340, which is enough days.
B.


Since 20 pages is halfway between 10 and 30 pages, the number of days must be halfway between 33 and 11 days.
C.


Since 10 pages are added each day from Plan A to Plan B, 10 days must be subtracted from the number of days needed in Plan A.
D.


Divide 326 ÷ 20 to get 16 R6. Round the quotient to the next greater whole number.
E.


Divide 326 ÷ 20 to get 17 R6. Round the quotient to the next greater whole number.
