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 =[tex]0.04\times 4000=[/tex]$160
Power company B sells of 4000 kwhr electricity=[tex]4000\times 0.03[/tex]=$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.
