24 miles = 326 gallons
divide each side by 24: 1 mile = 13.583 gallons
round: 13.6 miles per gallon
First term (a) = -15
common difference(d)= -9-(-15)
= -9+15=6
So,
12th term(a12)= a +(n-1)d
= -15+(12-1)×6
= -15 + 11×6
= -15+66
= 51
Answer:
The rate of change is 4.6 tickets/hour.
Step-by-step explanation:
The equation that represents the ticket sales is the equation of a line:
y = 4.6*x - 12.2
The equation of any given line can be writen by the following formula:
y = m*x + b
Where "m" is the slope of the line, or the rate of change, while b is the value for "y" when "x" is zero. Therefore in this case the rate of change is the number multiplying "x", so 4.6 tickets/hour.
Answer: It's A.
