We estimate that Jack can do 3 chemistry problems and 6 math problems in an hour, while Paula can do 4 chemistry problems and 7 math prob- lems in an hour. There are 1 chemistry problems and 17 math prob- lems. Set up and solve a system of two linear equations to determine how long Jack and Paula should work to do these problems. What is the matter with the solution? Propose a solution that makes more sense.
