(72 + 75 + 82 + 94 + x)/5 = 85
72 + 75 + 82 + 94 + x = 85*5
323 + x = 85*5
x = 85*5 - 323
x = 102

answer:
you need to get 102 in your 5th test, to get an overall score of 85, but that's probably impossible, because most tests have a maximum score of 100. if so, it means you cannot raise your overall average to 85, sorry !
