  1. 1. What are the 3 things needed to be an algebraic expression? 2. What is a verbal expression? Write as an algebraic expression. 3. 18 less than by 3 times d 4. 15 times the sum of a number x and 10 5. Write 4x + 5 as a verbal expression. Bell Ringer 10 – 3 3rd period

  2. Review 14 – 19 from homework 14. Books:A used bookstore sells paperback fiction books in excellent condition for $2.50 and in fair condition for $0.50. The expression 2.50x + 0.50f represents the cost of buying x excellent-condition paperbacks and f fair-condition paperbacks. a. Find the cost of purchasing 5 excellent-condition and 3 fair-conditioned books. 2.50 (5) + 0.50(3) 12.50 + 1.50 = $14.00 The cost of 5 excellent-condition and 3 fair-conditioned books will be $14.00.. Packet Level 2 Question #14packet

  3. 15. It is believed that ¾ of our dreams involve people that we know. The expression ¾d describes the number of dreams that feature people that you know if you have d dreams. • Use the algebraic expression to predict the number of dreams that include people you know out of 28 dreams. ¾d = ¾(28) = Out of 28 dreams, I predict 21 of my dreams will inlcude people I know.

  4. 16. Books:Akira bought one new book for $20 and three used books for $4.95 each. Write and evaluate an expression to find how much money the books costs. 1(20) + 3(4.95) = 20 + 14.85 = $34.85 The books would cost $34.85. Packet Level 2 Question #16

  5. 18. Car Rental: Important Facts: 1. Company charges $36 per day plus $0.50 per mile over 100 miles. 2. She rents the car for 5 days and drives 180 miles. a. Write a numerical expression for how much it will cost her to rent the car. $36(5) + $0.50(80) = b. Evaluate the expression. $180 + $40 = $220 She will pay $220 for the 5 day rental. Packet Level 3 Question #18

  6. 19. Music: Important Facts: 2 options Concert pass: $40 per concert Music Pass: pay $100 and see any concert for $10 a. Write an algebraic expression for how much a concert pass will cost. Let c represent the number of concerts, 40c will be the cost of a concert pass. Packet Level 3 Question #19 a and b

  7. You want to see 4 bands. How much will it cost for a music pass? $100 + 10c $100 + 10 (4) = $100 + $40 = $140 It will cost $140 to see 4 bands with a music pass. How much will it cost for a concert pass? $40c $40 (4) = $160 It will cost $160 to see 4 bands with a music pass.

  8. C. Write a brief paragraph explaining which pass is the better buy. What arguments can we make? Packet Level 3 Question #18c

  9. Parentheses and other grouping symbols • Parentheses, brackets [ ] braces { } and fraction bar --- • Exponents • Multiplication/Division (from Left to Right) • Addition/Subtraction (from Left to Right) 1-2 Order of Operations

  10. Packet finish 12a, b, e and i, 13d, 17b 12a. 35 - 3  8 = 35 – 24 = (Multiplication) 11 (Subtraction) 12b. 18 ÷ 9 + 2  6 = 2 + 2  6 = (Division) 2 + 12 = (Multiplication) 14 (Addition) Continue working as a team
