a. 37.9%, decrease
b. 37.9%, increase
c. 27.5%, decrease
d. 27.5%, increase
Find the total cost to the nearest cent.

To solve this, we need to calculate the percent change from 29 students to 40 students and determine if it is an increase or decrease.

### Step-by-Step Solution:

1. **Find the change in value:**
   \[
   \text{Change} = 40 - 29 = 11
   \]
   
2. **Calculate the percent change:**
   \[
   \text{Percent change} = \left( \frac{\text{Change}}{\text{Original value}} \right) \times 100
   \]
   \[
   \text{Percent change} = \left( \frac{11}{29} \right) \times 100 \approx 37.9\%
   \]

3. **Determine if it is an increase or decrease:**
   Since the value increased from 29 to 40, this is an **increase**.

Thus, the correct answer is:

**b. 37.9%, increase**
