Question: 395

Selection Method Number of States
Election 22
Gubernatorial appointment 11
Legislative appointment 2
Missouri Plan 15

5. There are four ways in which state judges are selected for their positions. One is by election, another is appointment by the governor (usually with the confirmation by the state legislature), and a third is appointment by the state legislature. The final way is a hybrid of the last two, called the Missouri Plan, in which a nonpartisan legislative committee recommends a list of candidates and the governor chooses from this list. The table above shows the number of states that engage in each process for the highest court of the state, usually called the state Supreme Court. What percent of states select judges using the Missouri Plan?

  • A. 17%
  • B. 30%
  • C. 33%
  • D. 43%

Strategic Advice: Don't spend too much time reviewing the context of the question. Focus on the last couple of sentences, which tell you what you're looking for.

Getting to the Answer: You need to find the percent of states that use the Missouri Plan. There are 15 states that use the Missouri Plan and 50 states total, so use the formula Whole × percent = part. The whole is 50, the percent is unknown so call it x, and the part is 15, resulting in the equation 50x = 15. Use division to find that x is 15 ÷ 50 = 0.3 = 30%.
