Given:
y = (x)(-1) -6
y = -15
Plug values in and solve for x:
-15 = -x - 6
-9 = -x
x = 9
You're just moving 6 up a decimal place each time, so the next 2 numbers in the sequence should be 60 and 600.
From 8.30 pm to 12 : 00
Difference = 12 : 00 - 08:30 = 3 : 30
3 hours 30 minutes = 3.5 hours.
Total for those hours = 3.5 * 1000 = $3500
From 12:00 to 1:00 am = 1 hour.
50% increase = 50% of 1000 = .50 * 1000 = 500
So it will increase to 1000 + 500 = $1500 per hour.
For the 1 hour extra, 1 * 1500 = $1500
Total = $3500 + $1500 = $5000
