9x + 1 = 5x - 15
Subtract 1 from both sides.
9x = 5x - 16
Subtract 5x from both sides.
4x = -16
Divide both sides by 4.
x = -4

Complete Question:
Suppose a local vendor charges $2 per hot dog and that the number of hot dogs sold per hour is given by , where is the number of hours since 10 AM:
a) Find an expression for the revenue per hour as a function of x, R(x)
b) Find and simplify, R(x(t))
Answer:
a) R(x) = 2x
b)
Step-by-step explanation:
a) This is a very trivial exercise.
The number of hot dogs sold per hour is given by x
Charge per hot dog = $2
An expression of revenue per hour,R, as a function of the number of hot dogs sold per hour, x, is therefore: R(x) = 2x
b)
R(x(t)) = 2(x(t))
