An economy consists of three workers: Larry, Moe, and Curly. Each works 10 hours a day and can produce two services: mowing lawns and washing cars. In an hour, Larry can either mow one lawn or wash one car; Moe can either mow one lawn or wash two cars; and Curly can either mow two lawns or wash one car.
a. Calculate how much of each service is produced under the following circumstances, which we label A, B, C, and D: • All three spend all their time mowing lawns. (A) • All three spend all their time washing cars. (B) • All three spend half their time on each activity. (C) • Larry spends half his time on each activity, while Moe only washes cars and Curly only mows lawns. (D)
b. Graph the production possibilities frontier for this economy. Using your answers to part a, identify points A, B, C, and D on your graph.
c. Explain why the production possibilities frontier has the shape it does.
d. Are any of the allocations calculated in part A inefficient? Explain.

One of the main reactions involved in the production of iron from iron(III) oxide as found in iron ore, proceeds according to the following balanced chemical equation:Fe2O3 (s) + 3 C(s) → 2 Fe(s) + 3 CO(g)
We will consider the reaction of iron(III) oxide and carbon on a gram scale, although the same stoichiometry applies on the tonne scale.
If 22.7 g of carbon is available, what is the maximum mass of iron which can be produced when the iron(III) oxide is present in excess?
