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?
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>__.
