the management of a hotel found that they will sell all 800 tickets at 4 dollars per per person for a hour concert for one night

Lesechka [4]

Answer:

Step-by-step explanation:

Let x represent the rate at which the ticket is sold and let y represent the number of tickets sold at that rate.

When x = 4, y = 800

This means that the income from gate takings at this rate is 4 × 800 = $3200

For each 1 dollar increase in the gate fee,management expects 100 fewer customers to buy tickets. It means that the amount earned would be (x + 1)(y - 100)

For the amount to be $3500, it means that

(x + 1)(800 - 100) = 3500

700(x + 1) = 3500

x + 1 = 3500/700 = 5

Therefore, management should charge $5 per person for gate fee so that it collects 3500 dollars from gate takings.

Find the value of X x=

Wewaii [24]

Answer:

x = 135°

Step-by-step explanation:

6 sided polygon = hexagon

The sum of the interior angles of a hexagon = 720°

⇒ 4x + 90 + 90 = 720

⇒ 4x = 720 - 90 - 90

⇒ 4x = 540

⇒ x = 540 ÷ 4

⇒ x = 135°
