Answer:
77
Step-by-step explanation:
If you add all the numbers you would get 251 and if you divide that by 3 you get 83.67. So what I did to get a mean of 82 was add those 3 numbers then the individual answer choice. so 72+97+82+77=328. 328/4 is equal to 82
B. 77
because (72 + 97 + 82 + 77) ÷ 4 = 82
