1. Your furniture store sells two types of dining room tables. The first, type A, costs $265 and you make a $25 profit on each o

Gnom [1K]

Let x represent the number of type A table and y represent the number of type B tables.
Minimize: C = 265x + 100y
Subject to: x + y ≤ 40
25x + 13y ≥ 760
x ≥ 1, y ≥ 1

From, the graph the corner points are (20, 20), (39, 1), (30, 1)
For (20, 20): C = 265(20) + 100(20) = $7,300
For (39, 1): C = 265(39) + 100 = $10,435
For (30, 1): C = 265(30) + 100 = $8,050

Therefore, for minimum cost, 20 of type A and 20 of type B should be ordered.

The following table shows the salary of 7 people in an office last year.

kotegsom [21]

Answer:

a. £24,714.29

b. £16,833.33

Step-by-step explanation:

The calculation of mean income is given below:-

Mean income = Total addition of salaries ÷ Number of workers

= £9,500 + £25,000 + £13,250 + £72,000 + £12,750 + £29,500 + £11,000

= £173,000 ÷ 7

= £24,714.29

Now,

the Mean income excluding Deva's salary:

= Formula of Mean income

= Total addition of salaries excluding Deva salary ÷ Number of workers

= (£9,500 + £25,000 + £13,250 + £12,750 + £29,500 + £11,000) ÷ 6

= £101,000 ÷ 6

= £16,833.33

11. The sales tax rate is 6.9%

Norma-Jean [14]

Answer:

40.1%

Step-by-step explanation:

I am assuming that 192 is in 100%.

100% = 192

I then represent the value that we are looking for with $x$ .

x% = 77

By dividing both equations (100% = 192 and x% = 77) and remembering that both left hand sides of BOTH equations have the percentage unit (%).

$\frac{100}{x} = \frac{77}{192}$

Now, of course, we take the reciprocal, or inverse, of both sides:

$\frac{x}{100} = \frac{7}{192}$

x = 40.1%

Thus making the answer: 40.1% of 192 is 77.

Select all of the following points that lie on the graph of f(x) = 7 - 3x.

ira [324]

The points that lie on the graph of f(x) = 7 - 3 x, are (-1 , 10) , (2 , 1)

and (0 , 7)

Step-by-step explanation:

To prove that a point lies on the graph of a line

Substitute the coordinates of the point in the equation of the line
If the left hand side is equal to the right hand side, then the point lies on the graph of the line

∵ The equation of the line is f(x) = 7 - 3 x

∵ f(x) = y

∴ y = 7 - 3 x

Point (-2 , 1)

∵ x = -2 and y = 1

- Substitute them in the equation

∴ 1 = 7 - 3(-2)

∴ 1 = 7 + 6

∴ 1 ≠ 13

∵ The left hand side is not equal the right hand side

∴ Point (-2 , 1) does not lie on the graph of the line

Point (-1 , 10)

∵ x = -1 and y = 10

- Substitute them in the equation

∴ 10 = 7 - 3(-1)

∴ 10 = 7 + 3

∴ 10 = 10

∵ The left hand side is equal the right hand side

∴ Point (-1 , 10) lies on the graph of the line

Point (2 , 1)

∵ x = 2 and y = 1

- Substitute them in the equation

∴ 1 = 7 - 3(2)

∴ 1 = 7 - 6

∴ 1 = 1

∵ The left hand side is equal the right hand side

∴ Point (2 , 1) lies on the graph of the line

Point (1 , 5)

∵ x = 1 and y = 5

- Substitute them in the equation

∴ 5 = 7 - 3(1)

∴ 5 = 7 - 3

∴ 5 ≠ 4

∵ The left hand side is not equal the right hand side

∴ Point (1 , 5) does not lie on the graph of the line

Point (0 , 7)

∵ x = 0 and y = 7

- Substitute them in the equation

∴ 7 = 7 - 3(0)

∴ 7 = 7 - 0

∴ 7 = 7

∵ The left hand side is equal the right hand side

∴ Point (0 , 7) lies on the graph of the line

The points that lie on the graph of f(x) = 7 - 3 x, are (-1 , 10) , (2 , 1)

and (0 , 7)

Neal buys a board game. He pays for the board game and pays \$1.54$1.54dollar sign, 1, point, 54 in sales tax. The sales tax rat

Stella [2.4K]

Answer:

$1.46

Step-by-step explanation:

To find the original price of the game, write a proportion. $1.54 is the amount after a 5.5% tax rate. This means he paid 105.5% on the original price.

$\frac{1.54}{y}=\frac{105.5}{100}$

Find y by cross multiplying numerator and denominator of each fraction.

1.54(100) = 105.5y

154 = 105.5y

1.46 = y
