Answer:
Step-by-step explanation:
Let x represent the number of miles after which the cost of both options will be the same.
You have two payment options. Option A is to buy a monthly pass for $30 and pay $0.80 per ride. This means that the total amount that you would pay for x miles if you use this option is
0.8x + 30
Option B is to pay $2.30 per ride. This means that the total amount that you would pay for x miles if you use this option is
2.3x
An equation to show after how many rides the cost will be the same would be
0.8x + 30 = 2.3x
2.3x - 0.8x = 30
1.5x = 30
