Last April, I posted a little exercise showing the per mile cost of gasoline ranging from $3 to $4 a gallon. Since we now at $4 gallon here's a chart depicting a $4 to $5 range.

$4.00 $4.50 $5.00
15 $0.27 $0.30 $0.33
17 $0.24 $0.26 $0.29
20 $0.20 $0.23 $0.25
22 $0.18 $0.20 $0.23
25 $0.16 $0.18 $0.20
27 $0.15 $0.17 $0.19
30 $0.13 $0.15 $0.17
32 $0.13 $0.14 $0.16
