Answer:

$1.2

Step-by-step explanation:

Let the cost per mile be x, and daily fee f.

Then we have equations:

  • 50x + f = 145
  • 90x + f = 193

Subtract the first equation from the second one:

  • 90x - 50x  + f - f = 193 -145
  • 40x = 48
  • x= 48/40
  • x= 1.2

Answer: the cost per mile is $1.2
