Answer:
$3, $2, True
Step-by-step explanation:
The change in the selling price of cola from $5 before the introduction of a tax by the government to $7 after the tax was introduced is simply a decision of the producer. This only has an effect on the volume of cases sold as the law of demand states that the higher the price, the lower the demand and vice versa. As such, if the consumer pays $7 per case after the introduction of tax and only $4 per case goes to the producer, the tax on a case is $3 ($7-$4).
The burden that falls on the consumer is $2 per case. Prior to the introduction of tax, the selling price per case (which goes to the producer) was $5. This is also the cost a consumer parts with for a case of cola. After the introduction of the tax, the consumer parts with $7 ($2 more than the cost before tax was introduced) while the producer gets $4 as against $5 (before tax was introduced). Hence the tax burden on the producer per case is $1 ($5-$4) and $2 per case on the consumer ($7-$5).
If all of the tax had been levied on the consumer, the producer would have received $5 per case (as received before tax was introduced) while the consumer would part with $8 per case ($3 as tax). This would have resulted in the consumer parting away with one more extra dollar. As such, with the law of demand that states that the higher the price, the lower the quantity demand, the effect of the tax on quantity sold would have been larger if it had been levied on the consumer only.
