Step-by-step explanation:
Question 1)
checks are stale dated when 6 months from the date of the check.
option---B
Question 2)
When comparing plans, you should look at your previous bills and estimate how they would have been different using another plan.
Option---A
Question 3)
The per minute charge is $0.10.
7pm-6am
There is a discount of 10%.
Phone was used for 400 minutes.
sales tax of 6%.
Hence total % he has to pay is 95.4%
6am-7pm
Phone was used for 130 minutes.
sales tax of 6%.
Hence total % he has to pay is 106%
Total amount he has to pay is given by:
[tex]\dfrac{(95.4\times 400+106\times 130)\times 0.10}{100}=$ 51.94[/tex]
Hence the total bill is: $51.94
Hence option C is correct.
Question 4)
if there is a power usage from 7pm-9am then there is a 15% discount. Hence we have to pay 85% of the total money in that time span.
In march there is a usage of 450 KWH from 7pm-9am
cost of 1 KWH=$0.05432
Hence, payment from 7 pm-9 am is given by:
[tex]\dfrac{85\times450\times0.05432}{100}[/tex]--------(1)
If there is a power usage from 9am-7pm then there is a premium of 20%.
Hence we have to pay 120% of the total money in that time span.
There is a usage of 465 KWH from 9am-7pm
Hence, payment from 9am-7pm is given by:
[tex]\dfrac{120\times 465\times 0.05432}{100}[/tex]-----------(2)
Hence,
Total payment in March= payment for 7pm-9am+payment for 9am-7pm
=$ 51.08 (Adding 1 & 2).
Option---- B
1. Option B is correct.
2. Option A is correct.
3. Option C is correct.
4. Option C is correct.
Further Explanation:
1. Stale check: The Check that is not presented at the bank within a period of six months from the date on which it has been drawn is referred to asa stale check. It is a valid check, but it may be considered as 'irregular' bill of exchange. A bank can refuse to honor the check unless its drawer confirms the payment by issuing a new Option or inserting a new payment date.
Therefore, option B is correct.
2. When two plans are compared then previous bills are used as the standard to compare the estimated cost under the new plan. When the comparison between the plans is made then the person should not enroll in the new plan without making a comparison, select the plan having the least cost and select the plan providing maximum benefits but compare it with the previous plan.
Therefore, option A is correct.
3. Calculate the total bill:
Total bill = $49 + $49 × .06
= $51.94
Thus, the total bill is $51.94.
Working note:
Calculate the charges for the call between 6 a.m – 7p.m:
Total charges = 130 minutes × $ 0.10 per minute
= $13
Calculate the charges for the call between 7 p.m – 6a.m:
Total charges = 400 minutes × $ 0.10 per minutes × (1 -0.10)
= $36
Calculate the total call charges:
Total call charges = $13 + $36
=$49
Therefore, option C is correct.
4. Caclulate the total call charges:
Total call charges = $30.31+ $20.77
=$51.08
Thus, the total bill is $51.08.
Working note:
Calculate the power charges for the call between 9 a.m – 7p.m:
Total charges = 465kwh× $ 0.05432 per kwh × (1 + 0.20)
= $30.31
Calculate the charges for the call between 7 p.m – 9 a.m:
Total charges = 450kwh× $ 0.05432 per kwh × (1 -0.15)
= $20.77
Therefore, option C is correct.
