i am on six grade. 2/5 of 150 is 60.10+10=20.20+60=80.150-80=70 half of 70 is 35. The answer is 35.
Multiply 150 by 2/5 to determine how many are blue, then add the number of blue, white and red cards, subtract from 150.
60 + 10 + 10 = 80...if half of them are pink, 80 - 40 = 40 yellow cards.
60 + 10 + 10 = 80...if half of them are pink, 80 - 40 = 40 yellow cards.
Thank you Reed and Nour
