APS DISTRICT HIGH SCHOOL MATHEMATICS CURRICULUM FRAMEWORK Course Title: Transition to College Math Course Number: 38010 Department: Mathematics ADS Number: 20354131 Prerequisites: Successful completion of Algebra II Length of Course: One Year Credit/PRI Area: .50 per Semester/Math Grade Level(s): 11 - 12 Important Notes: This course is not open to students who have completed Algebra II with a grade of B or better. This is a course for college-intending students who have already attempted high school courses in Algebra I and Geometry with unsatisfactory results . This course requires student access to a graphing calculator. COURSE DESCRIPTION: In Transition to College Math the student approaches the basic concepts and techniques from Algebra I and Geometry through numerical computation in concrete problem settings. Graphing is used to strengthen numerical intuition and to give concrete representation of functional relationships. The goal is to increase the readiness of the student to do college-level work in mathematics, and therefore, to open career options to him/her that might otherwise remain closed. Although references in parentheses following each performance standard align with the National Council of Teachers of Mathematics Standards (NCTM), the State of New Mexico Mathematics Standards (NM), and the Albuquerque Public Schools Mathematics Standards (APS), it is expected that by the time the student takes this course, he/she has already met or exceeded the standards. TRANSITION TO COLLEGE MATH 10.1.10 Albuquerque Public Schools 03/04 STRATEGIES: The “Illustrations” column in the Program of Studies provides exemplars of the performance standards, strategies, and best practices suggested by mathematics teachers in the Albuquerque Public Schools (APS). ASSESSMENTS: Assessments may include: authentic and performance-based assessment, cooperative learning, teacher observations, checklists, test and exams, formal and informal writing, small group and full class discussions, oral and multimedia presentations, individual and group projects, demonstrations, and portfolios. Assessments are based on appropriate rubrics. SUGGESTED TEXTBOOKS AND INSTRUCTIONAL MATERIALS: Current state adopted mathematics textbooks Supplemental materials Graphing calculators Computer software SUGGESTED TITLES/AUTHORS WEB SITES: Rubistar4teachers.com Nctm.org Approved by HSCA: TRANSITION TO COLLEGE MATH 10.2.10 Albuquerque Public Schools 03/04 STRAND I: GLOBAL MATHEMATICS PROCESSES CONTENT STANDARD: The student understands and uses mathematical processes.

The student follows through the steps to determine quantity discounts and profits for the sale of a manufactured product. Often businesses give a discount on products to encourage large sales. A clock radio company gives Wal-Shop Stores a $0.15 discount on each radio over 100 that they purchase. The regular wholesale price on orders less than 100 is $90.00. If they buy more than 100, the price for each radio decreases. Complete the chart below. 10.3.10 Price for each radio with discount $90.00 $90.00 – 5(0.15) = ? $90.00 – 15(0.15) = ? $90.00 = ? $90.00 – 100(0.15) = ? $90.00 = ? Amount owed to manufacturer $9000 = (100 x $90) ? = (105 x $89.25) ? = (115 x $ ) ? = (130 x $ ) ? = (200 x $ ) ? = (400 x $ ) What would be some of the factors used to determine the manufacturing cost of the radio? List as many factors of the manufacturing costs as you can. Discuss your list with classmates and add to your own if possible. Complete the following table for the cost of manufacturing radios at $60 each.

Amount owed by Wal-Shop – Cost to produce = Profit $9000 – 6000 = $3000 $9371.25 – 6300 = $3071.25 What do you notice about the amount that Wal-Shop pays to the manufacturer for 400 radios in the first table compared to the “cost to produce” the 400 radios in the second table? Does the clock radio company make any profit on 400 radios? Predict what happens to the company’s profit if 405 radios are sold to Wal-Shop at the discounted rate. Make another row on the tables if necessary. Graph P(x) = 45x - .15x2 on a graphing calculator. This is the function which describes profit for this problem. Find the maximum profit (vertex). Explain how this relates to the tables and the predictions that you made for the profits. Does this company need to set a limit on the number of radios that can receive a discount?
