Answer:
It will cost $36.38 to travel 8.9 miles.
Step-by-step explanation:
In order to get how much it will cost to travel 8.9 miles, you need to first set up a linear equation (in slope-intercept form, which is 
). You can do this with what the problem has given us. Since there's a flat fee of $3, that is the y-intercept or the 
slope-intercept form. Then there is $3.75 added for every additional mile traveled, making it the slope or the 
in slope-intercept form. That makes the equation look like:
The 
in that equation represents how far you traveled. Therefore in order to find out 8.9 miles, plug in 8.9 for .
Simply solve the equation and you will have how much it will cost to travel 8.9 miles.
Now add the like terms:
Since it needs to be rounded to the nearest cent, you will round to the nearest tenth:
Therefore, it will cost $36.38 to travel 8.9 miles.
1/4 because you just divde the numerator and the denominator by 12

*I evaluated the determinants using Sarrus' rule (see last picture):
∆= aei +bfg +cdh -gec -hfa -idb
*The symbol '∆' (delta) is usually used to denote a determinant.
