Let’s go through each part of the problem step-by-step.

### Given Data:
| Month     | Price Change |
|-----------|--------------|
| September | +1.20        |
| October   | -0.08        |
| November  | +0.74        |
| December  | +1.43        |
| January   | -2.11        |

### Solutions:

#### a. What is the total change in gas price over 5 months?
To find the total change, we add up all the price changes:

\[
1.20 + (-0.08) + 0.74 + 1.43 + (-2.11) = 1.18
\]

**Total Change:** +1.18

#### b. What is the difference between the September and January price?
This asks for the change from September to January. We take the January value and subtract the September value:

\[
-2.11 - 1.20 = -3.31
\]

**Difference between September and January:** -3.31

#### c. What is the difference between the October and January price?
This time, we find the difference between the January and October values:

\[
-2.11 - (-0.08) = -2.11 + 0.08 = -2.03
\]

**Difference between October and January:** -2.03

### Summary of Answers:
- **a.** Total change over 5 months: **+1.18**
- **b.** Difference between September and January: **-3.31**
- **c.** Difference between October and January: **-2.03**
