TEACHING A teacher has 15 weeks in which to teach six chapters. Write and then solvean equation that represents the number of lessons the teacher must teach per week ifthere is an average of 8.5 lessons per chapter.LONG DISTANCE For Exercises 24 and 25, use the following information.Gabriel talks an average of 20 minutes per long-distance call. During one month, he makeseight in-state long-distance calls averaging $2.00 each. A 20-minute state-to-state call costsGabriel $1.50. His long-distance budget for the month is $20. 8 4 8 2 8 4873946 Alg1 CH01 EP3Copyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc.24.
