Answer:
A score of 117 is needed, which Is not possible since the test is over 100.
Step-by-step explanation:
The other 3 scores are 85, 94,84 . Let's x be the 4th score he must score.
Therefore ( 85 + 94 + 84 + X)/4 =95
Then 263+X /4 =95
Cross mutiplying 4*95=263+X
Therefore X= 380-263
X= 117 which is not possible since the test score is over 100.
A). Simply, subtract 100 percent minus 65 percent, which gives you the answer 35 percent.
b). So, to find the total number you add 280 plus 65 percent, which gives you the answer, 462.
c). To find this, simply subtract 462 minus 280, which gives you the answer, 182.
Hope this helps!
