No calculators please. Can you show all steps so I can easily follow

Question 7: A) If y' = 3(30 - y) and y(0) = 15, when will y(x) = 28? B) If y' = 5 -60y and y(0) = 2, what is y()? C) If y' = k(M - y), y(0) = 1000, y'(0) = -2, and limx-+ y(x) = 350, solve for y' and y. D) Taylor makes a cup of coffee and leaves it on her kitchen counter. Her coffee cools according to Newton's Law of Cooling. Initially, it is 210 F and her kitchen is 65 F. After 2 minutes, her coffee is 195.F. When will her coffee be 160 F
