Core Content Standards
CCSS.Math.Content.HSA.REI.A.2 Solve simple rational and radical equations in one variable, and give examples showing how extraneous solutions may arise.
CCSS.Math.Content.7.RP.A.2.c Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as \(t=pn\).
Standards for Mathematical Practice
CCSS.Math.Practice.MP1 Make sense of problems and persevere in solving them.
