Question

Kelsey wants to compare the number of blouses that she owns a total of 30 blouses. 20% of them are blue. Five of them are red. 30% of them are white. The rest are pink. How many blouses are pink?

Answer 1

Let's start by finding the number of blue, red, and white blouses:

Number of blue blouses = 20% of 30 = 0.2 x 30 = 6
Number of red blouses = 5
Number of white blouses = 30% of 30 = 0.3 x 30 = 9

Now we can find the total number of blue, red, and white blouses:

Total number of blue, red, and white blouses = 6 + 5 + 9 = 20

Finally, we can find the number of pink blouses by subtracting the total number of blue, red, and white blouses from the total number of blouses:

Number of pink blouses = Total number of blouses - Total number of blue, red, and white blouses
Number of pink blouses = 30 - 20
Number of pink blouses = 10

Therefore, Kelsey has 10 pink blouses.
