The following table gives the cost, C(n)C(n), of producing a certain good as a linear function of nn, the number of units produced. Use the information in this table to answer the questions that follow it. nn (units) 75 100 125 150 C(n)C(n) (dollars) 10000 10125 10250 10375 (a) Evaluate each of the following expressions. Give economic interpretations of each. C(150)=C(150)= , which tells us C(150)−C(100)=C(150)−C(100)= , which tells us C(150)−C(100)150−100=C(150)−C(100)150−100= , which tells us (b)Estimate C(0)C(0). What is the economic significance of this value? (c)The fixed cost of production is the cost incurred before any goods are produced. The unit cost is the cost of producing an additional unit. Find a formula for C(n)C(n) in terms of nn, given that: Total cost=Fixed cost+Unit cost⋅Number of unitsTotal cost=Fixed cost+Unit cost⋅Number of units C(n)=

1. Countries across the world have been reporting the number of people who are confirmed to have Covid-19 and the number of people who have died with the disense. The graphs below show such numbers for Italy between January and October 2020. The blue line depicts the number of confirmed cases of Covid-19 and the red line the number of deaths. We call these two C(t) and D(t) respectively, where t is time measured in days since 5 January 2020. (So t =0 is the start of 5 January 2020-Le. midnight on 4 January 2020 and t= 148 would be the start of June, midnight of 31 May 2020.)
