Question

if cokeand pepsi are good substitutes explain under quantity demanded what happens when the price of coke is doubled

Answer 1

Two goods are substitutes in demand if, when the market price of the first good rises, the demand of the second good also rises, and vice-versa.
If coke and pepsi are good substitutes, when the price of coke is doubled, the demand for coke will decrease and demand for pepsi will increase, as the quantities of substitute goods demanded are inversely related (if the quantity demanded of one good increases, quantity demanded of other good decreases and vice-versa).
