Answer:

99

Step-by-step explanation:

Relative to his desired average, Pablo's scores are ...

-6, +3, +2, -3

In order for his average grade to be 95, the sum of all of these deviations and the one on his last test must be zero

-6 +3 +2 -3 +x = 0

x = 4

Pablo must get a 95+4 = 99 on his last test to have a 95 average.

Answer:

the answer is 97 if you're rounding but 99 if you want exactly 95

Step-by-step explanation:

if you add all the previous grades up it'll add up to 376 and then when you add 97 and then divide it by 5 (the total amount of assignments) it'll add up to 94.6 which rounds up to a 95 unless you want it a 95 exactly which would probably be 99
