## DragIT - Elasticity

In this section you can check that you know all the elasticity formulae. In the exercises below, you need to drag the blue buttons on the right onto the orange target areas to build the relevant elasticity formula. Have a go at each in turn. Try to get them right straight away, rather than by trial and error!

### Price elasticity of supply

### Price elasticity of demand

*N.B. A way of remembering this formula is to think of 'dinner (D) on your plate (P)'. In other words demand divided by price.*
