Why did persphone have to live with hades for 7 months and with demeter on earth for 5 months(in greek myths)

She ate three pomegranate seeds.

Pomegranates are food of the underworld. Since she ate three seeds she has to live with hades for 3 months of the year. For that three months Demeter her mother roams the Earth making plants and crops die, and harsh weather occurs. Winter comes for 3 months and when Persephone returns summer, spring and autumn come.

changes in factors like average income and preferences can cause an entire demand curve to shift right or left. this causes a higher or lower quantity to be demanded at a given price. demand curves relate the prices and quantities demanded assuming no other factors change. it is important for consumers to know this information, because it is crucial for them to know what they can afford and can't afford. i hope this .
