Answer 1

They should company A because when company B adds the extra charge you have to pay $220 and company A is only $160.

Answer 2

Answer:

Power company A

Step-by-step explanation:

We are given that

Power company A sells of  1 Kwhr  electricity=$0.04

Power company  B sells  of  1 kw hr electricity=$0.03

Power company B additional  monthly charge for electricity=$100

Total business uses electricity in 1 month=4000 kwhr

We have to find which company should used by me.

Power company A sells  of  4000 kwhr electricity =$0.04\times 4000=$$160

Power company B sells of  4000 kwhr  electricity=$4000\times 0.03$=$120

Power company B sells  of 4000 kwhr electricity=120+100=$220

Hence, Power company A should used by me because it is cheaper than  company B.
