Answer:
C. 3
Explanation:
The decision to use public or private transport is individual and depends on the tastes and preferences of each consumer. If there is a proposal to stimulate the use of public transport, it is necessary to affect these preferences, which are often associated with costs.
Measure 1 would only be feasible if a study showed that there is room for tariff reduction. Public transport should be used, but it should be sustainable without relying on subsidies.
Measure 2 may be adopted, as rising private transportation costs such as tolls, fares and so on may force people to decide to use public transport, but this is a more extreme measure that affects other sectors and I would not recommend it.
Measure 3 would be recommended because it is a stimulus to the consumption of public transport. If annual passes provide discounts, consumers' perceptions may change as public transport may become more economically attractive.

Answer:
a. Product X = 3.50 years
Product Y = 3.25 years
b. Product Y
Explanation:
The cash flows for the two products as well as the balance at the end of each year is given as follows:

For both products, the payback period is reached between the third and fourth year.
Product X:

Product Y:

Under the payback method, the alternative that presents the shortest payback period should be selected. Therefore, Product Y should be selected.
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.
