An arena receives $1,700 per event for 12 concerts. If the costs for this sponsorship total $14,000, what is the profit margin for the concert sponsorship?

Answers

Answer:

total profit margin for all 12 concert is $6,400.

profit margin for all one concert is $533.33

Step-by-step explanation:

Amount of money received for one event = $1700

Total no of concert = 12

Total money received for 12 event = Amount of money received for one event * Total no of concert

Total money received for 12 event = $1700 *12 = $20,400

Total cost of sponsorship = $14,000

Profit margin is the difference money invested and money earned.

here total investment is $14,000

Total money earned is $20,400

Therefore profit margin = money earned - total investment

= $20,400 - $14,000 = $6,400

Therefore total profit margin for all 12 concert is $6,400.

However to calculate profit margin for one concert we can simply divide the total profit margin for all 12 concert by no of concert (i.e 12)

profit margin for one concert = total profit margin for all 12 concert/total no of concert = $6,400/12 = $533.33

profit margin for all one concert is $533.33

Answers

B, A, B, D

to calculate the slope m use the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 7, - 2) and (x₂, y₂ ) = (9, 4)

m = $(4+2)/(9+7)$ = $(6)/(16)$ = $(3)/(8)$

repeat with (x₁, y₁ ) = (5, - 6) and (x₂, y₂) = (- 1, 8)

m = $(8+6)/(-1-5)$ = $(14)/(-6)$ = - $(7)/(3)$

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = $(1)/(8)$ x - 1 is in this form

with slope m = $(1)/(8)$

To find the y- intercept , let x = 0, in the equation

x = 0 : y = 0 - $(10)/(7)$ = - $(10)/(7)$ ← y- intercept

Final answer:

The slopes of the lines between the given pairs of points are 3/8 and -7/3 respectively. The slope of the line Y = 1 / 8x - 1 is 1 / 8 and the y-intercept of the equation Y = 7 / 2x - 10 / 7 is -10 / 7.

Explanation:

The slope between two points is found by using the formula m = (y2 - y1) / (x2 - x1). Let's calculate for the first two. For (-7, -2) and (9, 4), the slope m = (4 - (-2)) / (9 - (-7)) = 6 / 16 =

3 / 8

. So, the correct answer is B. For the second pair of points (5, -6) and (-1, 8), m = (8 - (-6)) / (-1 - 5) = 14 / -6 = -

7 / 3

. So, the answer is A. The slope of the line of an equation in the form of y = mx + b is the coefficient of x (m), so for the line Y = 1 / 8x - 1, the slope is

1 / 8

. The answer is B. The y-intercept (b) is the constant term in the equation y = mx + b, so for the equation y = 7 / 2x - 10 / 7, the y-intercept is -

10 / 7

. The answer is D.
