The formula to find markup amount

A new car has a sticker price of $22,150, while the invoice price paid on it was $18,780.
Original price of new car = $18,780
Sticker price of new car = 22,150
Change in price = 22,150 - 18,780 = 3370
Markup = 
= 
= 0.179446
Markup percentage = 0.179446 * 100 = 17.94%
The first one is 90
The second one is 108
I'm not sure but I think it's the right answer.

Answer:
Table 3; Blue graph; y = -4; 2x-3y = 7.
Step-by-step explanation:
Table 3 is a linear relationship because the y-coordinates, or outputs, change by the same rate throughout the table. A constant rate of change defines a linear function.
The blue graph is linear because it is a straight line.
The equation y = -4 is linear because it is the equation of a horizontal line at -4. A function with a line for a graph is linear.
The equation 2x-3y = 7 is linear because it is written in standard form of a linear function, Ax+By = C (in this case A = 2, B = -3 and C = 7).
Answer by JKismyhusbandbae: So to find the pattern we can subtract 49 and 42 to get 7 which should be our pattern to double check add 49 plus 7 to get 56 so 56 plus 7 equals 63.
