T costs Charlie's Car Repair Shop $27 to change the oil The shop charges their
customers $40 for an oil change. What is
the percent of markup in the cost of an
oil change?

Is it increase or decrease.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
