This week's POW
HAPPY GROUNDHOG'S DAY!
1. Every year on February 2nd in Punxsutawney, PA, Groundhog Phil is called upon to predict how much more winter there will be. If Phil sees his shadow there will be six more weeks of winter, but if he does not see his shadow spring is near. In 2006 Phil saw his shadow. If Phil’s shadow was 25 inches long (when he stands on his back legs) at the same time that a 12 foot tree cast a 15 foot shadow, how tall was Phil, in inches, in 2006?
2. Groundhog Phil’s cousin Henry lives in Moundsville with his family. At the beginning of 2006, Moundsville had a population of 2500 groundhogs but by the beginning of 2008 the population had grown to 3025 groundhogs. If the annual percentage of growth was the same in 2006 as it was in 2007, how many groundhogs lived in Moundsville at the beginning of 2007?
3. Groundhog Henry is digging a new tunnel in a flat field outside of his home. He starts by digging 3 ft straight down and then digs north 4 times the distance that he dug down. At this point Henry digs straight west for 17 ft before running into a boulder. Since he doesn’t know how big the boulder is, he backs up 1 ft and digs 3 ft straight up to the surface. How far is the end of Henry’s tunnel from the beginning of Henry’s tunnel?

Mixture Problems and Review for Test
1.) Mixture Problems, chapter 7, lesson 7 - Set I and II
2.) Review for test - Set II
The Chapter 7 Test is on Tuesday
3.) POW - Pick one option
Option 1: 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.
Option 2: 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.
Option 3: 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.
