Today’s “scavenger hunt” review activity. The question is in the bottom box, and the answer is in the top box of the next page. Have a great three day weekend.

Test 3 Scavenger Hunt (PDF version in case the Word Doc doesn’t work for you)

**Date**: Wednesday, November 14 (approx: 2:25pm to 3:30pm)

**Practice Questions**: https://artofproblemsolving.com/wiki/index.php?title=AMC_8_Problems_and_Solutions

Quarterly 1 (Mon, 10/29) – Graphing calculators will be permitted throughout the entire test

Quarterly 1 Review Sheet Answer Keys. **The answer keys also include explanations**. Enjoy the weekend!

Due Monday: Day-26-Word-Problems-Age-Coin-Solutions

**Note**: A change has been made to Problem 7. The total amount was originally stated as $42.15. The correct amount has been changed to $2.15.

Activity 1

(a) Create an expression for the red line shown. As an extra challenge, only part of the red line is shown.

(b) Create an expression for the blue line shown. As an extra challenge, only part of the blue line is shown.

(c) Create an equation by setting the expression for the red line equal to the expression for the blue line. Solve this equation. What do you notice about the answer and its relationship to the graph?

Activity 2

Do not open activity 2 until you have completed activity 1 and discussed it with at least one other person at your table. https://student.desmos.com/?prepopulateCode=t2rmdg

Activity 3

If you finish early, try these:

This is an overview of our solving equations unit. Don’t panic if you’re not sure how to solve some of these questions – we will be tackling specific skills in the coming week (fractions tomorrow and Friday, negatives on Monday, miscellaneous review on Tuesday, and then lots of word problems).
