A band is performing at an auditorium for a fee of $1500.
In addition to this fee, the band receives 30% of each $20 ticket sold.
The maximum capacity of the auditorium is 800 people.

a. Write an equation that represents the
band’s revenue R when x tickets are sold.

b. The band needs $5000 for new equipment.
How many tickets must be sold for the band to earn enough money to buy the new equipment..

Think and reason about this. Create a table. Does your answer make sense?
Remember y=mx+b

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
