Answer:
InsuranceRates.smokerCharge
Explanation:
To set the baseCost variable to the value of the class variable smokerCharge, the developer needs to replace
Decimal baseCost = XXX;
with
Decimal baseCost = InsuranceRates.smokerCharge;
This is done using the class reference type.
The smokerCharge should be declared in the InsuranceRates class, at first.
For example Ball b;
And then, a new instance of the object from the class is created, using the new keyword along with the class name: b = new Ball();
In comparing to the example I gave in the previous paragraph, the object reference in the program is:
InsuranceRates rates = new InsuranceRates();
Because the smokerCharge is coming from a different class, it can only be assigned to the variable baseCost via the InsuranceRates class to give:
Decimal baseCost = InsuranceRates.smokerCharge;
