When the price of a commodity increases, it is expected that the quantity consumed will decrease. This is because consumers tend to look for cheaper alternatives or reduce their demand for the commodity altogether. In this case, we will look at the effect of a price increase from 5 per unit in 1990 to 7.50 per unit in 1995 on the quantity consumed.



The extent to which a change in price affects the quantity demanded is measured by the price elasticity of demand. If the price elasticity of demand is high, then a small change in price will result in a large change in quantity demanded. On the other hand, if the price elasticity of demand is low, then a change in price will have little effect on the quantity demanded.



Based on the information provided, we can assume that the commodity in question is not a necessity but rather a luxury item. This is because if it were a necessity, then the price increase would have little effect on the quantity consumed as consumers would still need to purchase the commodity regardless of the price.

Assuming that the price elasticity of demand is high, we can expect that the quantity consumed will decrease significantly. This is because a price increase of 50% is quite substantial, and consumers will likely look for cheaper alternatives or reduce their demand for the commodity altogether.



In conclusion, we can expect that the quantity consumed of the commodity in question will decrease due to the price increase from 5 per unit in 1990 to 7.50 per unit in 1995. The extent of the decrease will depend on the price elasticity of demand for the commodity. If the price elasticity of demand is high, we can expect a significant decrease in the quantity consumed.

Nothing will change
