Answer:
Find the rate of change by dividing the value of one term by the value of the preceding term, in your problem:
$15/$10 = 3/2 or 1.5, this is your rate of change
1.5 ($15) = $22.50

but cant be less than 3 and greater than 4 at the same time
Step-by-step explanation:
Answer:
y= 4x + (-16)
Step-by-step explanation:
The slope of the given lime is m=4
x-intercept of the parallel line: (4,0)
plug that into the equation y= mx+b to find that b= -16
since the slope stays the same for parallel lines, and we just found b, we have the new line equation
Answer:
$17.5
Step-by-step explanation:
The operator, for a round-trip fare of $20, carries an average of 500 people per day.
It is estimated that 20 fewer people will take the trip, for each $1 increase in fare.
Therefore, for $x dollars increase in fare, 20x less people will take the trip and at that time the total fare F is given by
F(x) =(20 + x)(500 - 20x) = 10000 + 100x - 20x²
For F(x) to be maximum, the condition is
Hence, 100 - 40x = 0
⇒ x = 2.5
Therefore, the fare of $(20 - 2.5) = $17.5 will maximize the total fare. (Answer)
