Answer 1

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:

$(83+79+79+88+88+88+88)$ ÷ $7$

This can also be written as:

[83 + 2(79) + 4(88)] × 1/7
