Respuesta :

Answer:

B

Step-by-step explanation:

He plays a total of 11 + 17 + 7 = 35 songs of which 7 are disco, thus

percent of disco = [tex]\frac{7}{35}[/tex] × 100% = [tex]\frac{1}{5}[/tex] × 100% = 20% → B

Answer:

B. 20%

Step-by-step explanation:

Sum = 11+17+7

        = 35

fraction of disco tunes = 7/35

percent of disco tunes = 7/35 x 100

                                      = 20%

Hope it helps you!!!
