Public Release Items: Public release items have appeared on MSA forms and then are released for public viewing and use. Releasing items is one step to ensuring that schools, districts, and other stakeholders understand how the content standards are assessed on the MSA.

Standard 1.0 Knowledge of Algebra, Patterns, and Functions

Topic B. Expressions, Equations, and Inequalities

Indicator 2. Identify, write, solve, and apply equations and inequalities

Objective a. Write equations and inequalities to represent relationships

Assessment limit: Use a variable, the appropriate relational symbols (>, ≥, <, ≤, =), and one or two operational symbols (+, -, ×, ÷) on either side and use whole numbers, fractions with denominators as factors of 100, or decimals with no more than three decimal places (0 – 500)

Selected Response Item

Valeri earned $12.50 per hour at her summer job.

If she earned $375 last week, which equation can be used to determine the number of hours (h) Valeri worked?

  1. 12.50 + h = 375
  2. 12.50h = 375
  3. 12.50(375) = h
  4. 12.50 ÷ 375 = h
