When does the elasticity of supply of commodity called equal to unity?

When a percentage change in price leads to the same percentage change in the quantity supplied. This means that supply is unit elastic

Explanation:

Price elasticity of supply measures the responsiveness of quantity supplied to changes in price of the good.

Price elasticity of supply = percentage change in quantity supplied / percentage change in price

Supply is unit elastic if a small change in price has an equal and proportionate effect on quantity supplied.

For example, a 20% increase in price leads to 20% increase in the quantity supplied

Elasticity of supply = 20% / 20% = 1

you had 23.00$ because 28 - 5 = 23 then put it in dollar form
