Adam can clean a room in 3 hours. If his sister Maria helps, they can clean it in 225 hours. How long will it take Maria to do the job alone?
2 2 = 12 Together time, 2 2 , needs to be converted to fraction 555
Adan:3,Maria:x,Total: 5 Clearlystatetimesforeachandtotal,usingxforMaria 12
1+1= 5 Usingreciprocals,addtheindividualtimesgivestotal 3 x 12
1
1(12x) + 1(12x) = 5(12x) 3 x 12
4x+12=5x −4x −4x 12=x It takes Maria 12 hours
Multiply each term by LCD of 12x
Reduce each fraction
Move variables to one side, subtracting 4x Our solution for x
Answer is - 12 hours

The difference between comparative advantage and absolute advantage is that: A. Comparative advantage measures opportunity cost and absolute advantage measures efficiency.
<h3>What is a comparative advantage?</h3>
A comparative advantage can be defined as the ability of a business firm or country to produce goods and services at a lower opportunity cost than their rivals (competitors) or trade partners.
<h3>What is an opportunity cost?</h3>
An opportunity cost is also referred to as alternative forgone and it can be defined as the value, profit or benefits that are given up and forfeited by an individual or business firm, in order to choose or acquire something that is deemed most significant at a particular point in time.
In this context, we can infer and logically deduce that the difference between comparative advantage and absolute advantage is that comparative advantage measures opportunity cost and absolute advantage measures efficiency.
