Answer: 50 teams

Step-by-step explanation:

       We will set up a proportion to solve.

[tex]\displaystyle \frac{30\%}{15\;\;\text{teams}} =\frac{100\%}{x\;\;\text{teams}}[/tex]

       A percent divided by 100 becomes a decimal.

[tex]\displaystyle \frac{0.3}{15\;\;\text{teams}} =\frac{1}{x\;\;\text{teams}}[/tex]

       Next, we will cross-multiply:

0.3x = 15

       Lastly, we will divide.

x = 50
