The market demand curve would be 1000 - 0.125Q.
<h3>How to calculate the demand curve?</h3>
It should be noted that the market demand curve will be the sum of the individual demand curve.
The market demand curve will be calculated thus. Mary’s demand curve is 5P = 5000 – 1.25QM. Here, p = 1000 - 0.25QM
Jack’s demand curve for donuts is given by P = 1000 – 0.5QJ. Helen’s demand curve is given by QH = 2000 – 2P. This will be P = 1000 - 0.5QH.
The slope will be:
= 0.5 × 0.25
= 0.15
The demand function of Jack and Helen are the same. The demand curve will be 1000 - 0.125Q.

The lower market price implies that there will be less area between the supply curve and the market price of the product.
Answer:
<em>because the existing models have been in place for so long, they are considered untouchable, the equivalent of an economic law.</em>
Explanation:
The rational economic model is even more widely used in economics because it is easier to measure. Although people have irrational behaviors, they are more subjective, which makes the rational model still the most used by the economy, because through it is possible to measure behavior patterns, statistical data and information relevant to the economy.
