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

Please explain how to solve, thank you!

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 20 25 30
