Answer:
$0.6/hour.
Step-by-step explanation:
See the table attached.
The table shows the total amount of money in a parking meter at different time intervals after it was repaired.
Now, at time 3 hours, there was $3.75 money.
And at time 7 hours, there was $6.15 money.
So, the average rate of change between Hour 3 and Hour 7 will be
= [tex]\frac{\textrm {Total inctrease in Money}}{\textrm {Total increase in Time}}[/tex]
= [tex]\frac{6.15 - 3.75}{7 - 3} = 0.6[/tex] dollars per hour. (Answer)
