Answer:
1. f(x) is the total cost
2. x is the hours spent on the internet
3. the base rate is 3.50
4. hourly charge is .75
5. 4.63
Step-by-step explanation:
1. f(x) is the total cost or the amount of money he has to pay
2. x is the hours spent on the internet, it is the time spent on the internet
3. the base rate is 3.50, or the minimum amount just to get connected
4. hourly charge is .75
5. Let x = 1.5 for the hour and a half
f(1.5) = .75(1.5) + 3.5
1.125+3.5
4.625
To the nearest cent
4.63
Answer:
In the given function [tex]f(x)[/tex] refers to the total charge for the Wi-Fi.
The variable [tex]x[/tex] represents each hour, presents the time. When we have time in a relation, it's always represented by [tex]x[/tex], because that's the independent variable.
The base rate for the internet connections is 0.75, because this is a linear function, and its slope is always the ratio of change.
We can find the hourly charge for using the service by replacing [tex]x=1[/tex] in the function:
[tex]f(1)=0.75(1)+3.50=4.25[/tex]
So, after one hour, the service would cost $4.25.
If Kyle uses the service for one hour and a half, the cost would be:
[tex]f(1.5)=0.75(1.5)+3.50=4.625[/tex]
Therefore, after one hour and a half, the service would cost $4.62.
