To calculate the price elasticity of demand using the midpoint formula, we follow these steps:

1. Identify the initial and final prices and quantities.
- Initial price (P1) = $10
- Final price (P2) = $12
- Initial quantity demanded (Q1) = 36
- Final quantity demanded (Q2) = 30

2. Calculate the percentage change in quantity demanded.
$$
\text{Percentage change in quantity demanded} = \frac{Q2 - Q1}{\frac{Q2 + Q1}{2}} \times 100
$$
$$
= \frac{30 - 36}{\frac{30 + 36}{2}} \times 100
$$
$$
= \frac{-6}{33} \times 100
$$
$$
= -18.18\%
$$

3. Calculate the percentage change in price.
$$
\text{Percentage change in price} = \frac{P2 - P1}{\frac{P2 + P1}{2}} \times 100
$$
$$
= \frac{12 - 10}{\frac{12 + 10}{2}} \times 100
$$
$$
= \frac{2}{11} \times 100
$$
$$
= 18.18\%
$$

4. Calculate the price elasticity of demand.
$$
\text{Price elasticity of demand} = \frac{\text{Percentage change in quantity demanded}}{\text{Percentage change in price}}
$$
$$
= \frac{-18.18\%}{18.18\%}
$$
$$
= -1
$$

Therefore, the price elasticity of demand when the price increases from $10 to $12 is -1. The correct answer is:

-1.
