Question

A company wants to decrease their energy used by 17% if their electric bill is currently $2200 a month what will their bill be if they are successful

Answer 1

Answer: $\ 1826$

Step-by-step explanation:

Given

The company wants to decrease its bill by 17%

The amount of the current bill is $\ 2200\ \text{per month}$

Percentage decrease is given by

$\Rightarrow \dfrac{\text{original-New}}{\text{original}}\times 100$

Suppose the new bill is x

$\Rightarrow \dfrac{2200-x}{2200}\times 100=17\\\\\Rightarrow 1-\dfrac{x}{2200}=0.17\\\\\Rightarrow 0.83=\dfrac{x}{2200}\\\\\Rightarrow x=\ 1826$
