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?

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

The linear equation that best fits the data is: y = 10x + 15.

<h3>How to Write the Linear Equation of a Data?</h3>

First, find the slope/unit rate (m) and the y-intercept/starting value, then substitute the values into y = mx + b.

Using two points on the graph, (1, 25) and (2, 35), find the slope (m):

Slope (m) = (35 - 25)/(2 - 1)

Slope (m) = 10/1

Slope (m) = 10

Substitute (x, y) = (1, 25) and m = 10 into y = mx + b to find b

25 = 10(1) + b

25 - 10 = b

b = 15

Substitute m = 10 and b = 15 into y = mx + b

y = 10x + 15
