Example Question #1 : Creating Equations✭

Jimmy has a collection of baseball cards. He wants to make at least $50.00 by selling some of them for$3.00 per card. Which inequality best represents this goal?

Explanation:

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 least $50.00 by selling some of them for$3.00 per card."

Let,

Since Jimmy wants to make "at least" $50.00, that means the inequality will have a greater-than or equal-to sign. From here, set up the general inequality and substitute the known values. Example Question #1 : One Variable Equations And Inequalities: Ccss.Math.Content.Hsa Ced.A.1 Jimmy has a collection of baseball cards. He wants to make at least$20.00 by selling some of them for $4.00 per card. Which inequality best represents this goal? Possible Answers: Correct answer: Explanation: 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 least$20.00 by selling some of them for $4.00 per card." Let, Since Jimmy wants to make "at least"$20.00, that means the inequality will have a greater-than or equal-to sign.

From here, set up the general inequality and substitute the known values.

Example Question #3 : Creating Equations✭

Jimmy has a collection of baseball cards. He wants to make at most $50.00 by selling some of them for$3.00 per card. Which inequality best represents this goal?

Explanation:

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 $50.00 by selling some of them for$3.00 per card."

Let,

Since Jimmy wants to make "at most" $50.00, 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 #1 : Creating Equations✭ Jimmy has a collection of baseball cards. He wants to make at most$20.00 by selling some of them for $4.00 per card.
