Answer: 
- Compound Interest ⇒ FV = PV x (1 + I ) ^N
- Simple Interest ⇒ FV = PV x I x N
Explanation:
With compound interest the rate of growth needs to be compounded which is why the time period is used to exponentially adjust it. 
With simple interest there is no compounding so the value is simply the interest that will be earned every period (which is a constant value) multiplied by the number of periods and the amount to be invested. 
 
        
             
        
        
        
Answer:
CALCULATE EXPENSES
Your first order of business is finding out exactly how much you’re spending each month. Do this by consulting your bank statements, receipts and financial files. Because some expenses are intermittent, such as insurance payments, you’ll get the most accurate financial picture if you calculate an average for six months to a year. Add up everything you spent for the last six to 12 months and then divide by the amount of months, which will give you your average monthly expenses.
Remember that being thorough when you add up expenses is important in creating a realistic budget. A forgotten bill really throws a wrench into your savings plan. When calculating your expenses, also factor in unexpected bills, such as unplanned car repairs. A good rule of thumb is to add an extra 10 percent to 15 percent. So if you’ve determined that you spend $1,500 a month, add $150 to $225.
 
        
             
        
        
        
Answer:
PLAN A:
(120 * 0.39) + (40 * 0.19) + 20 = $74.40
PLAN B:
(120 * 0.49) + (40 * 0.14) + 20 = $84.40
PLAN C:
$20 + $75 = $95 ;
PLAN A is optimal from 0 to 192 minutes 
PLAN C is optimal from 192 minutes onward ;
Explanation:
PLAN A :
Service charge = $20
Daytime = $0.39 per minute 
Evening = $0.19 per minute 
PLAN B :
Service charge = $20
Daytime = $0.49 per minute 
Evening = $0.14 per minute 
PLAN C :
Service charge = $20
225 minutes = $75
Minutes beyond 225 = $0.36 per minute 
A.) 
Determine the total charge under each plan for this case: 120 minutes of day calls and 40 minutes of evening calls in a month.
PLAN A:
(120 * 0.39) + (40 * 0.19) + 20 = $74.40
PLAN B:
(120 * 0.49) + (40 * 0.14) + 20 = $84.40
PLAN C:
$20 + $75 = $95
b. If the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal?
PLAN A:
20 + 0.39D = 95
0.39D = 95 - 20
D = 75 / 0.39
D = 192.31
