Example Question #421 : High School: Algebra
Jimmy has a collection of baseball cards. He wants to make at most $15.00 by selling some of them for $1.75 per card. Which inequality best represents this goal?
To set up the inequality that represents Jimmy's situation, first identify what is given in the word problem and then translate it into mathematical terms.
"Jimmy has a collection of baseball cards. He wants to make at most $15.00 by selling some of them for $1.75 per card."
Let,
Since Jimmy wants to make "at most" $15.00, that means the inequality will have a less-than or equal-to sign.
From here, set up the general inequality and substitute the known values.
Example Question #11 : Creating Equations✭
There are a total of 80 firefighters in a town. There are 4 fire departments in the town: North, South, East, and West. The North Department has 23 firefighters. The East Department has 13 firefighters. Let W represent the number of firefighters in the West Department and S represent the number of firefighters in the South Department. Which equation best illustrates this situation?
To find the equation that represents this particular situation, the word problem will need to be translated into mathematical terms.
