A grocery store sells 2,700 cans of soup each year. A supermarket sells ten times as many cans of soup. How many cans of soup does the supermarket sell each year?

The supermarket sells 2,700 x 10 = <<2700*10=27000>>27,000 cans of soup each year. Answer: \boxed{27,000}.

To find out how many cans of soup the supermarket sells each year, we need to multiply the number of cans the grocery store sells by 10.

The grocery store sells 2,700 cans of soup each year.
So, the supermarket sells 10 * 2,700 cans of soup.

Calculating this, we get:
10 * 2,700 = 27,000

Therefore, the supermarket sells 27,000 cans of soup each year.
