1. The easiest way to save for your emergency fund is to use your____.
B. discretionary monies


2. When computing how many hours you need to work at a second job to meet a savings goal, you should___.

A. calculate the realized income at your primary job

Answer:

1. Option B

2. Option A

Explanation:

1. Discretionary income is basically the money that is left behind with an individual for his/her expenditure on recreational activities, vacations, nonessential goods and services etc. after paying all taxes and meeting out all essential personal necessities.  

Hence, in order to save for emergency it would be better to use discretionary monies instead of spending on luxury and comfort.  

2.  

Realized income is the actual earnings in the form of wages and salary. Thus a person needs to analyze his/her realized income so that he/she could work out a plan to determine extra money requirement. And based on this additional requirement, working hours can be determined based on hourly rate/charges.
