Example 1 Make a Function Table WORK Asha make $6.00 an hour working at a grocery store. Make a function table that shows Asha’s total earnings for working 1, 2, 3, and 4 hours. Interactive Lab: Function Machines Answer:

1.A 2.B 3.C 4.D Example 1 MOVIE RENTAL Dave goes to the video store to rent a movie. The cost per movie is $3.50. Make a function table to find the amount Dave would pay for renting 1, 2, 3, and 4 movies. A.$3.50, $7.00, $10.00, $14.00 B.$3.50, $7.50, $10.50, $14.50 C.$3.00, $6.00, $9.00, $12.00 D.$3.50, $7.00, $11.50, $15.00

Example 2 READING Melanie read 14 pages of a detective novel each hour. Write an equation using two variables to show how many pages p she read in h hours. Make a table to display the sequence.

Example 2 Answer: p = 14h WordsNumber equals14 pagestimesnumber of pages of hours. read VariableLet p represent the number of pages read. Let h represent the number of hours. Equationp = 14h

1.A 2.B 3.C 4.D Example 2 A.m = 55 + h B.m = 55h C.m = 55 – h D.mh = 55 TRAVEL Derrick drove 55 miles per hour to visit his grandmother. Write an equation using two variables to show how many miles m he drove in h hours.

Example 3 READING Melanie read 14 pages of a detective novel each hour. Use the equation p = 14h (p is how many pages she reads in h hours) to find how many pages Melanie read in 7 hours. p = 14hWrite the equation. p = 14(7)Replace h with 7. p = 98Multiply. Answer: 98 pages

1.A 2.B 3.C 4.D Example 3 A.9.16 miles B.61 miles C.49 miles D.330 miles TRAVEL Derrick drove 55 miles per hour to visit his grandmother. Using the equation m = 55h, find how many miles Derrick drove in 6 hours.
