Answer:
The correct answer option is E. [83 + 2(79) + 4(88)] × 1/7.
Step-by-step explanation:
We are given the quiz average, test average and final average for Sabra's grades for a class.
Given that her test average counts twice as much as her quiz average and final exam counts twice as much as her test average for her overall average:
[tex](83+79+79+88+88+88+88)[/tex] ÷ [tex]7[/tex]
This can also be written as:
[83 + 2(79) + 4(88)] × 1/7
