What values should I plug in for the P, the QD, and the QS values in these equations for elasticity of demand and supply? The demand and supply equations are:

QD=15-10P

QS=40P-50

The image contains equations related to elasticity in economics. The equations are as follows:

1. **Price Elasticity of Demand (E<sup>D</sup>):**

   \[
   E^D = \frac{\Delta Q^D}{\Delta P} \times \frac{P}{Q^D} = \frac{1}{\text{slope}} \times \frac{P}{Q^D}
   \]

   - **ΔQ<sup>D</sup>/ΔP**: Change in quantity demanded over the change in price.
   - **P/Q<sup>D</sup>**: Price over quantity demanded.
   - **1/slope**: The reciprocal of the slope of the demand curve.

2. **Price Elasticity of Supply (E<sup>S</sup>):**

   \[
   E^S = \frac{\Delta Q^S}{\Delta P} \times \frac{P}{Q^S} = \frac{1}{\text{slope}} \times \frac{P}{Q^S}
   \]

   - **ΔQ<sup>S</sup>/ΔP**: Change in quantity supplied over the change in price.
   - **P/Q<sup>S</sup>**: Price over quantity supplied.
   - **1/slope**: The reciprocal of the slope of the supply curve.

These formulas are key to understanding how the quantity demanded or supplied of a good responds to changes in price. The arrows indicate that these formulas are important for further explanation in the educational content.
