1. Data and projections from the Centers for Medicare and Medicaid Services from 2000 to 2018 indicate that the annual per capita out-of-pocket expenses for health care can be approximated by

y = 30.65x + 667.43 (dollars)

2. To earn an A in a course, a student must get at least a 90 average on four tests and a final exam, with the final exam weighted twice that of any one test. If the four test scores are 93, 69, 89, and 97, what is the lowest score the student can earn on the final exam and still get an A in the course?
