Answer:

9 shirts

Step-by-step explanation:

20% of the shirts were blue

20% of 30 is 6

6 shirts were blue

1/2 of the shirts were black

1/2 = 50%

50% of 30 is 15

15 shirts are black

15 + 6 = 21

30 - 21 = 9

(or you could add the percentages to get 70%, and get 30%. 30% of 30 is 9.)

Hope this helps!
