Need again when you see the =c7*$b$3 formula, what will happen when it is copied to the cell directly below the active cell using the fill handle?           a. both cell references will remain the same.   b. the c7 cell reference will remain the same and $b$3 will increase to $b$4.   c. the c7 cell reference will increase to c8 and $b$3 will increase to $b$4.   d. the c7 cell reference will increase to c8 and $b$3 will remain the same.  

Idon understand these and need some ! ?

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called.write a constructor for the above class that initialized both variables to zero.write a tostring to display both the tank and speed when the car is printed.modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter.write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.
