Hello!
The easiest way to solve this would be to convert 6 4/5 to a decimal. We know that to convert a fraction to a decimal, we must divide the numerator by the denominator.
4 / 5 = 0.8
0.8 + 6 = 6.8
So, 6 4/5 is 6.8 as a decimal.
See how it's easier now that we've converted the mixed number to a decimal?
There could be many numbers between 6.8 and 7. Some examples are:
6.81, 6.82, 6.83, 6.9, etc.
Answer:
A. $12
Step-by-step explanation:
For a quadratic of the form ax²+bx+c, the axis of symmetry is given by ...
x=-b/(2a)
For your quadratic function, the axis of symmetry is ...
s = -(2400)/(2(-100)) = 12
The function has its extreme value on the axis of symmetry. Here, the leading coefficient is negative, so the parabola opens downward. That means the extreme value is a maximum.
Profit will be a maximum at a selling price of $12.
Answer:
-8
Step-by-step explanation:
The answer is -8 because y=4 so 4-12=-8
