The points in each table lie on a line. Find the slope of the line.

Valentin [98]

Answer:

Step-by-step explanation:

Given table:

x -1 1 3 5

y -2 0 2 4

Unknown:

Slope of the line = ?

Solution:

Each x and y pair on the table lies on the line. Therefore, we can use them to find the slope;

Slope = $\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

let us take;

x₁ = -1 x₂ = 3

y₁ = -2 y₂ = 2

Insert the parameters and solve;

Slope = $\frac{2 - (-2)}{3- (-1)}$ = $\frac{4}{4}$ = 1

The slope of the line is 1

A restaurant averages ales of $120,000 when serving 20,000 guests. The restaurant's variable costs when 20,000 is $90,000. The c

Katarina [22]

Answer: Restaurant's monthly breakeven point in sales is $31333.

Step-by-step explanation:

Since we have given that

Number of guests = 20,000

Average sales = $120,000

Contribution margin per guest = $1.50

Let the number of sales be 'x'.

Cost per sales would be

$\dfrac{120000}{20000}\\\\=\$6$

Margin contributed by 2000 guests would be

$1.50\times 20000\\\\=\$3000$

So, Revenue function would be

$6x+3000$

Fixed monthly cost = $ 50,000

Variable cost for 20000 guests = $90000

So, Variable cost per sale would be

$\dfrac{90000}{20000}\\\\=\$4.5$

So, Cost function would be

$4.5x+50000$

Breakeven point would be

Cost function = Revenue function

$6x+3000=4.5x+50000\\\\6x-4.5x=50000-3000\\\\1.5x=47000\\\\x=\dfrac{47000}{1.5}\\\\x=\$31333.33\\\\x=\$31333$

Hence, Restaurant's monthly breakeven point in sales is $31333.
