Jackson and his grandfather constructed a model for a birdhouse. Many of their neighbors offered to buy the birdhouses. Jackson decided that building birdhouses could help him earn money for his summer camp, but he is not sure how long it

will take him to finish all of the requests for birdhouses. If Jackson can build birdhouses in hours, write an equation

that will allow Jackson to calculate the time it will take him to build any given number of birdhouses, assuming he works

at a constant rate.

a. Write an equation that you could use to find out how long it will take him to build any number of birdhouses.
