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
Answer:

So option (b) is correct option
Explanation:
We have given value of operation PV = $25.00
WACC, that is
= 11.50% = 0.1150
It is grow at a constant rat of 7 % so g = 0.07
We have to find the value of 
We know that value of operation is given by

So 

So option (b) is correct option
Answer:
Current ratio= 1.3977
Explanation:
Current Ratio:
It is the measure of company ability to pay short term debits of one year. It also tells how company can increase its current assets.
