Drupady [299]

Answer:

Correct choice is B

Step-by-step explanation:

Let x% be your final test score, then the average of all test scores is

$\dfrac{96+77+74+x}{4}.$

Since you must have an average between 80% and 89%, then

$80\le \dfrac{96+77+74+x}{4}\le 89,\\ \\320\le 247+x\le 356,\\ \\73\le x\le 109.$

X is measured in percent, then the greatest value of x can be 100%. You get that

$73\%\le x\le 100%.$
