Answer: The true cost of the jacket is $27 dollars.
Step-by-step explanation: To find the cost of the jacket after the discount just do 30 X .1 to get 3. Then take 3 and subtract it from 30. The mistake the clerk made was he probably just saw 10% and did 30-10=20. The clerk might have brain damage because this is like 5th grade math.

Answer:
f⁻¹(x) = (1/2)x +5
Step-by-step explanation:
In y = f(x), swap the variables, then solve for y. The expression you get is f⁻¹(x).
... y = 2x -10
... x = 2y -10 . . . . . . swapped variables
... x +10 = 2y . . . . . add 10
... (1/2)x + 5 = y . . . . divide by 2
... f⁻¹(x) = (1/2)x + 5 . . . . . . rewrite using function notation
