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 20142014 was $280,900\$280{,}900. This was $10,700\$10{,}700 more than 1414 times the price in November 19641964. What was the median price of a new home in November 19641964?

  1. Read the problem carefully. We are comparing a present house price to a past house price.

  2. Identify what to find: the median price of a home in 19641964.

  3. Name the unknown: Let pp = the median price of a new home in 19641964. The phrase "$10,700\$10{,}700 more than 1414 times the price in November 19641964" translates to the algebraic expression 14p+10,70014p + 10{,}700.

  4. Translate into an equation: The price in 20142014 was $280,900\$280{,}900, so: 14p+10,700=280,90014p + 10{,}700 = 280{,}900

  5. Solve the equation. First, subtract 10,70010{,}700 from both sides: 14p=270,20014p = 270{,}200 Divide both sides by 1414: p=19,300p = 19{,}300

  6. Check: Is $10,700\$10{,}700 more than 1414 times $19,300\$19{,}300 equal to $280,900\$280{,}900? 14(19,300)+10,700=?280,90014(19{,}300) + 10{,}700 \stackrel{?}{=} 280{,}900 270,200+10,700=?280,900270{,}200 + 10{,}700 \stackrel{?}{=} 280{,}900 280,900=280,900280{,}900 = 280{,}900 \checkmark

  7. Answer: The median price of a new home in November 19641964 was $19,300\$19{,}300.

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.
