Martin Luther King Jr. was born on January 15, 1929. His birthday is celebrated each year as a national holiday on the third Monday of January. What is the earliest date in January the nation can celebrate Martin Luther King Jr.’s birthday? What is the latest date in January the nation can celebrate Martin Luther King Jr.’s birthday? What is the probability Martin Luther King Jr.’s actual birth date falls on the third Monday in January? Express your answer as a common fraction.

On August 28, 1963 Martin Luther King Jr. led a march of approximately 250,000 people from the nation’s Capitol to the Lincoln Memorial in Washington, D.C. His speech at the Lincoln Memorial included increasing the minimum wage from $1.15 per hour to $2.00 per hour. Congress increased the federal minimum wage from $1.15 to $1.25 per hour in 1963. The federal minimum wage did not reach $2.00 per hour until 1974. What is the positive difference between the percent increase in the minimum wage passed by congress in 1963 and the percent increase requested by Martin Luther King Jr. in his speech? Express your answer to the nearest tenth.

Assume the federal minimum wage was $1.15 per hour on September 1, 1963 and $2.00 per hour on September 1, 1974. Assume the federal minimum wage increased annually on September 1 by r percent of the previous year’s wage for each of the years during this time period. What is the value of r? Express your answer as a decimal to the nearest tenth.
