Answer:
Sam is 10 years old.
Explanation:
Lets just say this was asked in 2020 meaning 5 years ago was 2015.
If Pete was 15 in 2015 and his age was 3x the age of Sam, Sam would be 5.
15/3= 5
Now that 5 years has passed since 2015 Sam is 10 and Pete is 20.
(15+5) + (5+5)
Adding the two ages in current times, the sum is 30.
20 + 10 = 30
(a) Microville has the absolute advantage producing cars. Because the most it can produce is 10 while Macroville can only produce 5.
(b) The opportunity cost is 5 cars if Macroville decides to use all of its resources and produce 20 boats.
(c) Microville has the comparative advantage in producing cars? Because its opportunity cost for 1 car is 1 boat while Macroville's cost for 1 car is 4 boats.
(d) If each country were to specialize in producing either cars or boats and then trade for the other product, Macroville makes 20 boats and Microville makes 10 cars. Each country produces the goods it has a comparative advantage in. Cars for Microville and boats for Macroville.
