Item A = 20% of overall grade Item B = 40% of 80 = 32% of overall grade Item C = 60% of 80 = 48% of overall grade Your grades were Item A, 57% Item B, 72% What is needed on Item C to get either 60% or 70% overall? So far you have (towards your overall grade) 57% of 20 = 11.4 72% of 32 = 23.04 11.4 + 23.04 = 34.44% of overall grade accomplished. To get 60, you need 25.56 more towards overall. 25.66 = 53.25% of 48. To get 70 you need 35.56 more towards overall. 35.56 = 74.1% of 48 You need 53.25% on Item C to get a 60%, you need 74.1% on Item C to get 70%.
