Technology is addicting and distracting, just take personal experience. Have you ever had a time when you were on the computer, on the phone, playing games, watching TV, etc. and time flew by? You were procrastinating and should have been doing something else? Were you ever multitasking and paid more attention to technology than what you should be doing? If so, then you have your answer, and from your own experience as well.
Add the following constants in the class definition, before the main method:
private final static float START_COST = 1.5f;
private final static float HIGH_TARIFF = 0.5f;
private final static float LOW_TARIFF = 0.25f;
private final static int FIXED_MINS = 2;
private final static int HIGH_TARIFF_MINS = 10;
Then add this to the main method you already had:
float price = START_COST;
if (x > FIXED_MINS) {
if (x <= HIGH_TARIFF_MINS) {
price += HIGH_TARIFF*(x-FIXED_MINS);
}
else {
price += HIGH_TARIFF*(HIGH_TARIFF_MINS-FIXED_MINS)
+ LOW_TARIFF*(x-HIGH_TARIFF_MINS);
}
}
System.out.printf("A %d minute call costs %.2f", x, price);
If you have 10 bits available then you can interpret any number in range ![[0,2^{10}-1]=[0,1023]](https://tex.z-dn.net/?f=%5B0%2C2%5E%7B10%7D-1%5D%3D%5B0%2C1023%5D)
.
The system therefore could represent the actual temperature of 39°C.
Hope this helps.
