A producer is said to have an absolute advantage over another producer when he required less amount of input to produce the same good compared to the other producer.
While a producer is said to have a comparative advantage over another producer when he produces his goods at a lesser opportunity cost compared to the other produer.
Here, time is one of the inputs used in production and Maria produces a scarf at a lesser time compared to Sofia. Thus, Maria has an absolute advantage over Maria in the production of scarves.
Therefore, the true statement is "<span>Maria has an absolute advantage over Sofia".</span>
First, convert all measurements to inches.
Box 1:
3ft(12in)=36in+6in=42in
Box 2:
4ft(12in)=48in+10in=58in
Box 3:
4ft(12in)=48in+5in=53in
Now, add the heights together.
42in+58in+53in=153in
Finally, convert added height to feet.
153in/12in=12 with a remainder of 9, so your final answer is 12ft 9in
