CHECK POINT 1 The average yearly salary of a woman with a bachelor’s degree exceeds that of a woman with an associate’s degree by $14 thousand. The Average yearly salary of a woman with a master’s degree exceeds that of a coman with an associate’s degree by $26 thousand. Combined, three women with each of these educational attainments earn $139 thousand. Find the average yearly salary of women with each of these levels of education. (These salaries are illustrated by the bar graph on page 370.)
