The elasticity of demand is a measure of how much the quantity demanded of a good responds to a change in price. If the elasticity of demand for cereal is 1, this indicates that the demand is unitary elastic.
When demand is unitary elastic (elasticity = 1), the percentage change in quantity demanded is equal to the percentage change in price.
In this case:
- Price increases by 25 percent.
- Therefore, the quantity demanded will decrease by the same percentage, which is also 25 percent.
So, the correct answer is:
**25 percent**
