Step-by-step explanation:
Given
[tex]D = 25 + 0.3X[/tex]
The question has missing details; as what's required is not stated.
However, since it is a linear equation, possible questions could be
1. Determine the slope
2. Determine the D-intercept
3. Calculate the amount in dollars for (say) 5 miles
An equation is represented as:
[tex]D = b + mx[/tex]
Where
[tex]b = D\ intercept[/tex]
[tex]m = slope[/tex]
By comparing: [tex]D = 25 + 0.3X[/tex] to [tex]D = b + mx[/tex]
[tex]b = 25[/tex] and [tex]m = 0.3[/tex]
This means that the slope is 0.3 and the d intercept is 25
To get the amount for 5 miles, we substitute 5 for x in [tex]D = 25 + 0.3X[/tex]
[tex]D = 25 + 0.3 * 5[/tex]
[tex]D = 25 + 1.5[/tex]
[tex]D = 26.5[/tex]
The cost of 5 miles is $26
Make use of the above explanation to solve the question
