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.

zalisa [80]

9/16 Cup of Brown Sugar

Step-by-step explanation:

Convert the 3/8 Cups of Brown Sugar to 6/16 to make division easier.

So for every 2/3 Cup of White Sugar you use 6/16 Cup of Brown Sugar.

So 1/3 a Cup of White Sugar would use 3/16 a Cup of Brown Sugar.

So 3/3 or 1 Cup of White Sugar would use 9/16 a Cup of Brown Sugar
