Answer:
x ≤ 217
Explanation:
The mean is found by adding each time and dividing by the amount of attempts.
If the mean has to be no greater than 200s and there are five attempts, than the total five attempts should total to no more than 200*5=1000s
The total sum of the first four attempts is 192+206+194+191=783
x must be equal to or less than 1000 - 783 = 217
