The given information compares the average salaries of both engineering majors and accounting majors to the average of marketing majors, so it makes sense to use the average salary of marketing majors as the "baseline".
x = average salary of marketing majors (thousands of dollars)
x+5 = average salary of accounting majors
x+24=average salary of engineering majors
x+(x+5)+(x+24)=245
3x+29=245
3x=216
x=72
ANSWERS:
average salary for marketing majors: x=$72,000
average salary for accounting majors: x+5=$77,000
average salary for accounting majors: x+24=$96,000
