The problem is asking for the percent increase in the cost of crude oil between two dates.

### Step 1: Identify the given values
- Cost on 9/2/2016: $44.20
- Cost the day before (9/1/2016): $43.52

### Step 2: Calculate the difference
The difference in the costs is:
\[
\text{Difference} = 44.20 - 43.52 = 0.68
\]

### Step 3: Calculate the percent increase
To find the percent increase, we use the formula:
\[
\text{Percent Increase} = \left(\frac{\text{Difference}}{\text{Original Price}}\right) \times 100
\]
The original price is $43.52. Substituting the values:
\[
\text{Percent Increase} = \left(\frac{0.68}{43.52}\right) \times 100 = 1.5625\%
\]

### Step 4: Round to the nearest hundredth of a percent
The percent increase rounded to the nearest hundredth is:
\[
1.56\%
\]

### Final Answer: 
The percent increase is **1.56%**.
