Answer:

y=-2500x+56500

Step-by-step explanation:

We need to write expression of the attendance in terms of the price of the tickets.  We can determine the percentage increase of the attendance by decreasing the tickets price. We can have two points:

(11,29000) and (9,34000)

We have calculate the slope:

m=(34000-29000)/(9-11)=-2500

Substitute point into:

y=mx+c

29000=-2500(11)+c

c=56500

The equation is:

y=-2500x+56500

where x is the ticket price and y is the attendance.

7x − 12 = 5x + 17<br> what is x?
Ksju [112]

Answer:

x = 14.5

Step-by-step explanation:

<u>Step 1:  Subtract 5x from both sides </u>

7x − 12 - 5x = 5x + 17 - 5x

2x - 12 = 17

<u>Step 2:  Add 12 to both sides </u>

2x - 12 + 12 = 17 + 12

2x = 29

<u>Step 3:  Divide both sides by 2 </u>

2x / 2 = 29 / 2

<em>x = 14.5 </em>

Answer:  x = 14.5

Dmitry_Shevchenko [17]

Answer:

The cost of the 7.5 lbs of walnuts be $2.16 .

Step-by-step explanation:

As given

It costs $3.45 to buy \frac{3}{4} lb of chopped walnuts.

i.e

Now calculate the cost of one pound .

Cost\ of\ one\ pound = \frac{3.45}{\frac{3}{4}}

Cost\ of\ one\ pound = \$ 0.2875

Now calculated the cost of the 7.5 lbs of walnuts .

Cost of 7.5 lbs of walnuts = 7.5 × 0.2875

                                           = $2.16 (Approx)

Therefore the cost of the 7.5 lbs of walnuts be $2.16 .
