Classwork – Example 1 Jackson’s Birdhouses Jackson and his grandfather constructed a model for a birdhouse. Many of their neighbors offered to buy the birdhouses. Jackson decided that building the birdhouses could help him earn money for his summer camp, but he is not sure how long it will take him to fill all of the requests for birdhouses. If Jackson can build 7 birdhouses in 5 hours, write an equation that will allow Jackson to calculate the time it will take him to build any given number of birdhouse. a. Write an equation that you could use to find out how long it will take him to build any number of birdhouses. Let B = # of birdhouses Let H = # of hours

b. How many birdhouses can Jackson build in 40 hours? 56 = 1B Jackson can build 56 birdhouses in 40 hours c. How long will it take Jackson to build 35 birdhouses ? H = 25 hours

d. How long will it take to build 71 birdhouses? H = 50.7 hours It will take Jackson 50 hours and 42 minutes to build 71 birdhouses.

Example 2 - Al’s Produce Stand Al’s Produce Stand sells 7 ears of corn for $1.50. Barbara’s Produce stand sells 13 ears of corn for $2.85. Write two equations, one for each produce stand that models the relationship between the number of ears of corn sold and the cost. Then use each equation to help complete the tables below. Al’s produce stand y = kx y = 0.21 x Barbara’s produce stand y = kx y = 0.22 x $2.94 $ $3.08$
