Ques 1) B

Ques 2) A

Ques 3) C

Ques 4) C

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:

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:

--------(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:

-----------(2)

Hence,

Total payment in March= payment for 7pm-9am+payment for 9am-7pm

                                       =$ 51.08   (Adding 1 & 2).

Option---- B
