A + s = 480......s = 480 - a
8a + 5s = 2892
8a + 5(480 - a) = 2892
8a + 2400 - 5a = 2892
8a - 5a = 2892 - 2400
3a = 492
a = 492/3
a = 164 <=== there were 164 adult tickets sold
100 + 0.50c = 1.50c <== ur equation
100 = 1.50c - 0.50c
100 = c....so he would have to sell 100 cups of coffee to break even

Answer:

Step-by-step explanation:
Given
per hour for 40 hours, weekly
per hour over 40 hours, weekly
Required
Determine f(x)
From the question, we have that
x represents hours worked
Earnings in 40 hours is: 40 * 10 = $400
Hours over 40 will be: x - 40
So, earnings during this time will be: (x - 40) * 15
Total earnings is:
