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}

Hoochie [10]

Answer:

The number of vials of type A insulin sold were _<u>21</u>__ and the number of vials of type B insulin sold were __<u>29</u>__.

Step-by-step explanation:

Let a = number of type A vials.

Let b = number of type B vials.

38.85a + 30.34b = 1695.71

a + b = 50

            38.85a + 30.34b = 1695.71

(+)        -38.85a - 38.85b = -1942.50

---------------------------------------------------

                               -8.51b = -246.79

b = 29

a + b = 50

a + 29 = 50

a = 21

Answer: The number of vials of type A insulin sold were _<u>21</u>__ and the number of vials of type B insulin sold were __<u>29</u>__.
