Basically speaking, a fractional notation is the same as a fraction itself. Thus, the best way to express the given problem in here would be to turn it into a fraction. Since the given variable is a mixed number, meaning that it is a whole number and a fraction combined, it can be turned into just a fraction or more specifically, an improper fraction. To do this, we have to take the denominator and multiply it to the whole number. After that, the product would be added to the numerator. The sum would be the new numerator and the denominator would remain the same. Thus, the answer would be 41/8

Answer:
Option C. 2
Step-by-step explanation:
Let
x ----> the number of days
y ----> the internet charges in dollars
we have

This is a proportional relationship between the variables x and y
The slope of the linear function is equal to the constant of proportionality k

The unit rate is the same that the slope 
so
The unit rate is $2 per day
therefore
The unit rate in the equation is 2
