Mary bought more than 72 pencils to distribute to children at an orphanage. She packs these pencils in gift boxes. If she packs 4 pencils each into x gift boxes, the inequality that represents this situation is?. The simplified form of the inequality is ?
For this case, the first thing we must do is define a variable. We have then: x: number of gift boxes. We then have to write the inequation that models the problem: "Mary bought more than 72 pencils" "she packs 4 pencils each into x gift boxes" We have then: [tex]4x \geq 72[/tex] Simplifying we have: [tex]x \geq 72/4[/tex] [tex]x \geq 18[/tex] Answer: the inequality that represents this situation is: [tex]4x \geq 72[/tex] The simplified form of the inequality is: [tex]x \geq 18[/tex]
