an education can be the key to higher earnings. In a U.S Census Bureau study, high school graduates earned $30,400 per year. Associate's degree graduates averaged $38,200 per year. Bachelor's degree graduates averaged $52,200 per year. Assuming a 50-year work-life, calculate the lifetime earnings for a high school graduate, associate's degree, graduate, and bachelor's degree graduate. What's the lifetime income difference between a high school and associate's degree? What about the lifetime income difference between a high school and bachelor's degree? LU 1-2(3), LU 1-2(2)
