Number of cases sent per year to the supreme court

Here's something... hope it helps :)

The Certiorari Act of 1925 gives the Court the discretion to decide whether or not to do so. In a petition for a writ of certiorari, a party asks the Court to review its case. The Supreme Court agrees to hear about 100-150 of the more than 7,000 cases that it is asked to review each year.

Where are the choices?
