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

Bezzdna [24]

Answer:

$732

Step-by-step explanation:

Given

$y \to profit$

$x \to widgets$

$y = -x^2 + 64x - 292$

Required

The maximum profit

First, we calculate the maximum amount of widgets that can be sold using:

$x = -\frac{b}{2a}$

Where:

$a = -1; b = 64; x = -292$

So, we have:

$x = -\frac{64}{2 * -1}$

$x = -\frac{64}{-2}$

$x = -(-32)$

$x = 32$

The maximum profit is:

$y = -x^2 + 64x - 292$

$y = -(32)^2 + 64 * 32 - 292$

Using a calculator, we have:

$y = 732$
