These are not too hard but the questions are rather too ambiguos! Well apart from the A part though!

Yes and thats why i already solved d A part myself because its very easy.

If you have answered question A yourself, I see question B and C to be even more simpler than A. Why not try attempting it and post the code for checking and corrections.

Question B

/**

public class YearlyProfit {
public double profit(double amount, double rate){
// I refuse to put time in the calculation since the programm indicate its yearly and that means time is 1 year
return amount*rate/100;
}
}


Since you answered question, I believe you can create an instance variable in another class or create main method in this very class and use it to check calculations of you chosen amount over range of 2% to 10% interest. (Hint : loop over 2 to 10 percent)

Qestion C

public static double VolumeNeeded(int stackNo, double stackLenght, double stackWidth, double stackHeight ){
return stackLenght*stackWidth*stackWidth*stackHeight*stackNo;
}

The simple explanation is, the minimum volume(may be volume of Bully Van) needed to trasport the number of stack(area * height) is volume of stack multiply by number of stacks they want to transport.

You can copy that method into a class with main or any class to create an instance of such class somewhere else and called with your argument passed to it. However it is a static method too so you can call it using the name of it class

Quite bussy now, will give u ans 2 qst D latter

thanks alot.
i actually did A using varibles, u can imagine hw annoying it can be. I have method lecture tomorow.

Just coming back. But that question isn't that clear to me. Is the initial amount already in the account or what?

no idea.

went for the method class and i am now even more confused

I can do nothing but to laugh. lol
