Let Kt denote the quantity of capital a country has at the beginning of period t. Also, suppose that capital depreciates at a constant rate d, so that dKt of the capital stock wears out during period t. If investment during period t is denoted by It, and the country does not trade with the rest of the world (the current account surplus is always zero), then we can say that the quantity of capital at the beginning of period t + 1 is given byKt+1 = (1 - d)Kt + ItSuppose at the beginning of year 0 that this country has 80 units of capital. Investment expenditures are 10 units in each of years 0, 1, 2, 3, 4, . . . , 10. The capital stock depreciates by 10% per year.(a) Calculate the quantity of capital at the beginning of years 0, 1, 2, 3, 4, . . . , 10.(b) Repeat part (a), except assume now that the country begins year 0 with 100 units of capital. Explain what happens now, and discuss your results in parts (a) and (b).

While studying for the engineering economy final exam, you and two friends find yourselves craving a fresh pizza. you can't spare the time to pick up the pizza and must have it delivered. "pick-up-sticks" offers a 1-1/4-inch-thick (including toppings), 20-inch square pizza with your choice of two toppings for $15 plus 5% sales tax and a $1.50 delivery charge (no sales tax on delivery charge).
