Question

The bar graph shows the average number of hours U.S college students study per week for seven selected majors. Study times are rounded to the nearest hour. The combined weekly study time for students majoring in

physics, English, and sociology is 50 hours. The difference between weekly study time for physics majors and English majors is 4 hours. The difference between weekly study time for physics majors and sociology majors is 6 hours. Find the average number of hours per week that physics majors,

English majors, and sociology majors spend studying.
