Solving a Word Problem for the Past Price of a Home
Apply the seven-step problem-solving strategy to a real-world word problem to find a past price given a current price using multiplication and addition.
Problem: US Census data shows that the median price of a new home in the U.S. in November was . This was more than times the price in November . What was the median price of a new home in November ?
-
Read the problem carefully. We are comparing a present house price to a past house price.
-
Identify what to find: the median price of a home in .
-
Name the unknown: Let = the median price of a new home in . The phrase " more than times the price in November " translates to the algebraic expression .
-
Translate into an equation: The price in was , so:
-
Solve the equation. First, subtract from both sides: Divide both sides by :
-
Check: Is more than times equal to ?
-
Answer: The median price of a new home in November was .
This problem applies the two-step equation framework to real-world financial data, highlighting how "more than" translates to addition and "times" translates to multiplication.
