Laura received a grant that will pay for 30% of her annual estimated tuition and a scholarship that will pay for her books. What is the minimum Laura should expect to contribute to her college education for all four years?

In order ot answer this question, we will assume that Laura will pay the same amount of tuition each year. If Laura receives a grant that pays the books and 30% of her annual tuition, then for four years, Laura pays 2.8 times the annual tuition only. Furthermore, she has to pay for her allowance as well.
