Sonia bought 30 t shirts at a clothing store. 20% of the t shirts were blue and 1/2 of the t shirts were black. How many of the
t shirts were neither black or blue?
1 answer:
9 T-Shirts
- Step-by-step explanation:
- There are 30 t shirts. 20% of the t shirts were blue and 1/2 of the t shirts were black.
- 20% is equivalent/ the same as 20/100 and simplified, 1/5. 1/2 black + 1/5 blue = 70/100 black and blue.
- This leaves 30/100(30%) remaining t shirts (neither black or blue). This leaves us to find 30% of 30 (shirts). 30% of 30 equals 9. 30/100 = 9/30.
