$52.50 and $69.51

Explanation:

You can set this up like a linear equation #y = mx +b#.
1. Identify your slope (x): $0.09 per mile.
2. Identify the y-intercept or flat base rate: $39.
3. Form the equation: #y = 0.09x + 39#
5. Plug in values:
#$0.09(150 mi) + $39 = $52.50#
#$0.09(339 mi) + 39 = $69.51#
