Answer 2

Answer:  The required number of kilowatt hours is 40.71.

Step-by-step explanation:  Given that Jessica’s electricity bill costs $32.44 per month plus $1.34 per kilowatt hour.

We are to find the number of kilowatt hours that she can use and keep her bill to no more than $87.

Let x represents the number of kilowatt hours that Jessica can use to keep her bill to no more than $87.

Then, according to the given information, we have

$32.44+1.34x\leq 87\\\\\Rightarrow 1.34x\leq 87-32.44\\\\\Rightarrow 1.34x\leq 54.56\\\\\Rightarrow x\leq \dfrac{54.56}{1.34}\\\\\Rightarrow x\leq 40.71.$

Thus, the required number of kilowatt hours is 40.71.
