At a local animal shelter there are 12 small sized dogs and 5 medium size dogs. every day, the small sized dogs are each given 12.5 ounces of dry food and the medium size dogs are each given 18 ounces of the same dry food. how many pounds of dry dog food does the shelter serve in one day? what conversion will you need to do to solve the problem?

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
