Sue's grade in her math class is related to the number of hours she studies. The rate of change of her grade, G(t), is proportional to (100 G), where t is measured in hours and G(t) is her grade after t hours of study. The highest grade is a 100. G(0) = 60, meaning she could get a 60 without any studying. After 10 hours Sue's grade would be an 80. How many hours would Sue need to study to get an A, which is a 90 or better? Round your answer up to the nearest hour. O 12 O 20 O 25 O 30

Sue's grade in her math class is related to the number of hours she studies. The rate of change of her grade, G(t), is proportional to (100 - G), where t is measured in hours and G(t) is her grade after t hours of study. The highest grade is a 100. G(0) = 60, meaning she could get a 60 without any studying. After 10 hours Sue's grade would be an 80. How many hours would Sue need to study to get an A, which is a 90 or better?
