Kim is a math and science tutor. She offers tutoring sessions that are 1, 1.5, 2, 2.5, or 3 hours long. The equation m= 15h + 30 represents her charge in dollars for a math session that is h hours long. For science, she charges the same one-time fee but a different hourly rate. She charges $105 for a 3-hour science tutoring session. Write an equation in slope-intercept form that represents the total charge, s, of a
science tutoring session that is h hours long, and find the reasonable range of that equation.
