In 2006, there were 12,440 starbucks stores worldwide. this is approximately 1126% more stores than 10 years earlier. How many S

Marizza181 [45]

Let's say there were "x" in 1996, therefore, "x" is the 100%.

10 years later, there are 12440, and that is 1126% "more" than "x", since "x" is 100%, 1126% more than that is 100% + 1126%, or 1226%.

so, 12440 is really 1226% of whatever "x" happened to have been back then in 1996.

now, since we know that 12440 is 1226%, what is "x" then?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
x&100\\
12440&1226
\end{array}\implies \cfrac{x}{12440}=\cfrac{100}{1226}\implies x=\cfrac{12440\cdot 100}{1226}$

Solving the inverses of these functions and applying the composite we obtain:

Note that (F⁻¹ о G⁻¹) also results in X (see second annex)

Explain why the numerical expression 4 less than 20 is written as 20-4 and not 4-20

Phantasy [73]

When converting English phrases into mathematical expressions/equations, we do things from left to right. That is why it's 4 - 20 instead of 20 - 4.

This rule is applied to division as well.

Answer:

I think that the answer would be C because you have to multiply the term at the top. This would mean you would not do C. Sorry if this is wrong. At least you have your eliminating process now. lol so doing C is out of the box, which makes C your answer.
