A. Write an inequality to model the problem
B. Solve the inequality. Show your work
C. Answer the question

Answer 1

A. sales * 12 != 145

B. s * 12 != 145
145/12 = 12
s != 12

Gabriela will make profit on her on her 13th sale.

Answer 2

she will make a profit after the 12th car.

explanation- x(15−3)−145>0 to find when she starts to make a profit:
So:
12x−145>0
12x>145
x>14512=12.08≈12
if x=13:
13⋅12−145=$11
