18. Assessment Focus Hendrik has a choice of 2 companies to rent a car. Company A charges $199 per week, plus $0.20 per kilometre driven. Company B charges $149 per week, plus $0.25 per kilometre driven. Determine the distance that Hendrik must drive for the two rental costs to be the same. a) Model this problem with an equation. b) Solve the problem. c) Verify the solution. Show your work. 19. Solve each equation. a) ~ (m + 12) = > (20 + m) b) (5 - 3t) =(t-2) C) (1 + 3r) = = 2 (2 - 3r) WINNIW 3 d) (6x + 5) =(20x -7) 20. Both Dembe and Bianca solve the equation: 3 x + = =x- 6 Dembe clears the fractions by multiplying each side by 12. Bianca clears the fractions by multiplying each side by 24. a) Solve the equation using each student's method. Compare the solutions. b) When you solve an equation involving fractions, why is it a good idea to multiply each side by the least common denominator
