Answer: 60
Step-by-step explanation: I did the math but sorry if this is wrong
You would get it wrong cause you haven’t answered anything
(67 + 68 + 78 + x) / 4 = 70
(213 + x) / 4 = 70
213 + x = 70 * 4
213 + x = 280
x = 280 - 213
x = 67
(213 + x) / 4 = 79
213 + x = 79 * 4
213 + x = 316
x = 316 - 213
x = 103
lowest u can make is 67, highest u can make is 100
That would be 156%. have a great day
