b) 40
c) 60
d) 50

Answer 1

To find the number of black shirts Ms. Grady has, we subtract the total percentage of pink, white, and blue shirts from 100%, then find 40% of 250 shirts, which equals 100 black shirts.

Step-by-step explanation:

The question asks us to calculate the number of black shirts Ms. Grady has in her closet. Ms. Grady has a total of 250 shirts. We are told that 25% are pink, 15% are white, and 20% are blue. To find the percentage of black shirts, we need to subtract the sum of the percentages of pink, white, and blue shirts from 100%:

• 100% - (25% + 15% + 20%) = 100% - 60% = 40%

Now, we calculate 40% of 250 shirts to determine the number of black shirts:

• (40/100) × 250 = 0.4 × 250 = 100

Therefore, Ms. Grady has 100 black shirts in her closet.
