Answer:

  • $30
  • 4 rides

Step-by-step explanation:

Let the number of rides be x

Then the cost will be:

  • Option 1: $30
  • Option 2: 3x + 18

Since the cost is same, we find x by following equation:

  • 3x + 18 = 30
  • 3x = 30 - 18
  • 3x = 12
  • x = 12/3
  • x = 4 rides

So cost of 4 rides is $30 for both options
