A journalist writes n articles and gets ₦200(n+7) for each article. If he gets 52000 altogether,how many articles did he write?

Let's first break down the given information into an equation:

The journalist writes n articles and gets ₦200(n+7) for each article.
The total amount he gets is 52000.

So, we can write the equation as:
200(n+7) = 52000

Now, let's solve for n:

200n + 1400 = 52000
200n = 52000 - 1400
200n = 50600
n = 50600 / 200
n = 253

Therefore, the journalist wrote 253 articles.
