The Cozy Car Company created a new model of car especially for Japan and Vietnam, which they start shipping to both countries at the same time.The company had shipped 222 of that model of car to Japan by the end of the first month, and the cumulative total of cars they've shipped triples each month.The company had shipped 555 of that model of car to Vietnam by the end of the first month, and the cumulative total of cars they've shipped increases by 111111 cars each month.In which month will the cumulative number of cars of that model shipped to Japan first exceed the cumulative total shipped to Vietnam?

We assume you intend that cars shipped to Japan are modeled by
j(n) = 2·3^(n-1)
and that those shipped to Vietnam are modeled by
v(n) = 5 + 11·(n-1)

The value of j(n) will exceed the value of v(n) in month 4.
