1.14x = 2x

x = (0.12) (1.14) x

Step-by-step explanation:

We are going to express the data in an equation form:

If x was the number of cases there was in 2000 ⇒currently there are 1.14x cases of measles.

But the question also tells us that the number of cases now is also 2 times what it was in 2000.

So we have that 1.14x = 2x

It also tells us that the number of measles back in 2000 was 12% of what it is now.

x = (.12) 1.14x

We can't really solve these equations since the problem doesn't give us any more information (I am assuming there was another part of the problem before this one that wasn't written here).
