When the price оf оrgаnic vegetаbles increаses frоm $4 to $5 per pound, the quantity demanded decreases from 10 to 6 pounds per week.

If income then increases to $1,200 and organic vegetable consumption increases to 8 pounds (at the new price of $5), calculate the income elasticity and classify the good.
