If you simplify each side of the equation you get this y= -4 - 3x/5
67.50 + 12.50 = 80
80/100 = 0,8 x 3 = 2.4
so, the total bill was 80 + 2.4 = 82.4

Answer:
X = 75
Step-by-step explanation:
Angle F and angle X are corresponding angles so they are congruent (equal)
Angle F and 105 form a straight line so they are supplementary angles, which means they add to 180
F+ 105 = 180
F = 180-105
F = 75
F = X = 75
