To solve
applications with subtraction, we will use the same plan that we used with addition. First, we need to determine what we are asked to find. Then we write a phrase that gives the information to find it. We translate the phrase into math notation and then simplify to get the answer. Finally, we write a sentence to answer the question, using the appropriate units.
The temperature in Chicago one morning was
degrees Fahrenheit. A cold front arrived and by noon the temperature was
degrees Fahrenheit. What was the difference between the temperature in the morning and the temperature at noon?
Solution
We are asked to find the difference between the morning temperature and the noon temperature.
Write a phrase.
the difference of 73 and 27
Translate to math notation.
Difference tells us to subtract.
Then we do the subtraction.
Write a sentence to answer the question.
The difference in temperatures was 46 degrees Fahrenheit.
The high temperature on
in Boston was
degrees Fahrenheit, and the low temperature was
degrees Fahrenheit. What was the difference between the high and low temperatures?
The weather forecast for June
in St Louis predicts a high temperature of
degrees Fahrenheit and a low of
degrees Fahrenheit. What is the difference between the predicted high and low temperatures?
Write the numbers so each place value lines up vertically.
Subtract the digits in each place value. Work from right to left starting with the ones place. If the digit on top is less than the digit below, borrow as needed.
Continue subtracting each place value from right to left, borrowing if needed.
Check by adding.
Practice makes perfect
Use Subtraction Notation
In the following exercises, translate from math notation to words.
In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,
When MP₁ becomes negative, TP start to decline.
Extuples Suppose that the short-run production function of certain cut-flower firm is given by: Q=4KL-0.6K2 - 0.112 •

Where is quantity of cut flower produced, I is labour input and K is fixed capital input (K-5). Determine the average product of labour (APL) and marginal product of labour (MPL)
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

What do you think is more important to focus on when considering inequality ?
sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏
Asui
it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs
Awais
thank you so much 👍 sir

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
