A company spends $15000 on advertising for a year, and then spends a third of that amount on advertising for another year.  What's the total amount the company spent on advertising for the two years?
How much is spent on advertising in the second year? ** 15000/3 = <<15000/3=5000>>5,000 is spent on advertisement in the second year.
What's the total amount the company spent on advertising for the two years? ** The total on advertisement for the two years is 15000+5000 = <<15000+5000=20000>>20000 dollars.
