Answer:
a. The effective price received by sellers is $0.40 per bottle less than it was before the tax.
Step-by-step explanation:
When government imposes tax on a product, a seller's margin on such a product falls which the seller tries to recover from the buyer by raising the price of the product.
In the given case, $1 is tax payable to government out of which the seller recovers $0.60 from the buyer via increased price. So, the remaining $0.4 tax is being paid by the seller out of his own pocket.
Effective price received refers to net amount received by the seller after deducting expenses and taxes. So, in the given case, the seller now receives $0.4 less per bottle than the receipts before such tax was imposed.
