Option One:
The first options costs only $0.0092/gram (a fraction of a penny)!
Option Two:
The second option costs only $0.0085/gram (cheaper than option one)!
Option Three:
This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore, 1,000g costs $5.65. Next, we set up the ratio as usual:
The third option costs $0.00565/gram.
Therefore, option three is the cheapest!
Hope this helps!

What is mean by Function?
A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines relationship between one variable and another variable.
We know that;
For a hyperbola ;
⇒ x² / a² - y² / b² = c²
where, a² + b² = c²
And, The directrix is the line, y = a² / c
and, the focus is at (0, c).
Here, We have;
⇒ c = 5,
⇒ a² = 9,
So We get;
⇒ b² = 5² - 9 = 16.
Thus, We get;
⇒ a = √9 = 3
⇒ b = √16 = 4

There are n + 7 whole numbers
Step-by-step explanation:
Here, we want to calculate the number of whole numbers between 0 and n + 7
Since n + 7 is a while number, what we shall do is to simply subtract 0 from it
Thus we have; n + 7 - 0 = n + 7
So there are n + 7 whole numbers between n+ 7 and 0
Answer:
n+7
Step-by-step explanation:
n+7-0=n+7?
