x = 1/9m good luck........
They sold 2000 student tickets and 0 regular tickets
The formula can be written in the form ...
... T = (original temperature) + x·(change in temperature each minute)
The problem statement gives you the original temperature (21 °C) and tells you the temperature after 12 minutes. You have to use that information to figure out the change in temperature each minute.
The change in temperature in 12 minutes is (75 °C) - (21 °C) = 54 °C. That is the change in 12 minutes, so the change in 1 minute will be 1/12 of that:
... 54/12 = 4.5
Using this value in the equation for T, we have
... T = 21 + 4.5x
Distance =960 kilometers
Graph the distance (960 kilometers) it traveled is on the y-axis
Time=4 minutes
Graph the time it travels on the x-axis
Divide total amount spent by total gallons bought:
47.82 / 16.9 = $2.83 per gallon
