1.15 - 1.19 = -0.04
-0.04 ÷ 1.15 = -0.034
-0.034 x 100 = -3.478%

1.51 - 1.15 = 0.36
0.36 ÷ 1.51 = 0.238
0.238 x 100 = 23.841%

2.79 - 1.51 = 1.28
1.28 ÷ 2.79 = 0.458
0.458 x 100 =45.878%

2.28 - 2.79 = -0.51
0.51 ÷ 2.28 = -0.223
-0.223 x 100 = -22.3%

The trend I see is that the prices change dramatically year by year.

Today the average gas price is $3.329

3.329 - 2.28 = 1.049
1.049 ÷ 3.329 = 0.315
0.315 x 100 = 31.510%
