Question

Pablo wants to get a grade of at least 95 in math this semesterSo far he has test scores of 89 98, 97 and 92. He will take his last test on Friday What is the lowest grade he can get on the test and still get a 95 this semester?

Answer 1

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

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

Answer 2

99

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.
