Is my calculation wrong? what could be the correction if so?, my activity asked me to find the quantity demand for each price in each point, i am not sure and very confused with my calculation, the instruction told me to solve it by using the demand function "Qd= 80-2p" so when i used it for the given 80 pesos (the amount of price), the quantity demand ended up becoming 80 too. but i think it sounds off bc i was taught that in the law of demand, it states that when the price is high, the quantity demand lowers.
