Question

A company wants to decrease their energy use by 15%. If their electric bill is currently $1,700 a month, what will their bill be if they are successful? Give your answer accurate to at least the nearest dollar.$

Answer 1

We will determine it as follows:

$x=1700-1700(0.15)\Rightarrow x=1445$

So, they will pay $1445 if they manage to decrease the consumption by 15%.
