Answer 1

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 x 4000 $160

Power company B sells of 4000 kwhr electricity=4000 x 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.
