a. stateTaxRate - A good variable name because it represents what it holds, the state sales tax rate, without being too wordy. Also correctly capitalized in camelcase.
b. txRt - A bad variable name because while short and simple, it is too hard to understand what the variable represents.
c. t - A very bad variable name if you plan on using the variable often. Far too short and you will forget what it represents and is needed for.
d. stateSalesTaxRateValue - A bad variable name because it is just too wordy. Cutting it down to A's variable name is much more reasonable
e. state tax rate - A bad variable name and probably invalid because it has spaces in the name.
f. taxRate - A good variable name if there are no other tax calculations other than state tax rate. Otherwise you would confuse state vs local tax rate or something, making it a bad variable name.
g. 1TaxRate - A bad variable name because the number 1 has no reason being in the variable name. It doesn't add anything to the name.
h. moneyCharged - A bad variable name because it is not specific enough in explaining why the money is being charged and what for.

Answer:
The following code are:
public void dissolve() {
setRed(getRed()+1);
setGreen(getGreen()+1);
setBlue(getBlue()+1);
alpha+=1;
}
Explanation:
Here, we define the void type function "dissolve()" inside it, we set three function i.e, "setRed()", "setGreen()", "setBlue()" and then we increment the variable "alpha" by 1.
Inside those three mutators method we set three accessor methods i.e, "getRed()", "getGreen()" , "getBlue()" and increment these accessor by 1.
The values will not be returned by the mutator functions, the accessor will be returned the values.
