Let us write both the plans in the form of equation:
1st plan: $75 + 0.20x , where x is the number of miles driven
2ns plan: 0.70x
To find the number of miles that Keiko would need to drive for the two plans to cost the same, we equate the equations and solve for x as;
=> 75 + 0.20x = 0.70x
=> 0.70x - 0.20x = 75
=> 0.50x = 75
=> x = 75 / 0.50 = 150 miles
Answer: 150 miles
