T.i.P.S.

In sixth grade, students modeled and solved onevariable, onestep equations and inequalities that represented problems, including geometric concepts. Students must model and solve onevariable, twostep equations, and inequalities with constraints or conditions. Students may use algebra tiles, pictorial models, and numbers to represent equations and inequalities. Equations and inequalities should include rational number coefficients and constants. A step only refers to an action involving both sides of the equation or inequality. Combining like terms on a single side of the equation or inequality does not constitute a step. Constraints or conditions may include the terms minimum, maximum, up to, no more than, no less than, etc.
Example

The price of oranges is $0.55 per orange at the Hidden Farmer’s Market. Lynne paid a total of $18.50, which included her oranges plus a $2.00 processing fee. What is an equation that represents the total amount Lynne spent on oranges for her trip to the farmer’s market?
