Jessica electricity bill costs $32.44 per month plus $1.34 per kilowatt hour. how many kilowatt hours can she use and keep her b
1 answer:
Jessica can use no more than 40 kilowatt hours.
To check this, we're going to start by subtracting the bill from 87 dollars.
This equals 54.56 dollars.
You then solve how many hours she can use by dividing.
You get a really big answer like 40.7164... since it needs to be a whole number and not a fraction of a number, round down.

Answer:

85%
Step-by-step explanation:
You are given the function
If n is the number of hours, then initially n=0 and
If S(n) is the function of exponential growth, then it can be represented as
where I is the initial amount, r -is the percent growth rate and n is the number of hours.
If b = 1.85, we can represent it as b = 1 + 0.85. Thus, the hourly percent growth rate of the bacteria would be 0.85=85%.
