Answer:
765 kids
Step-by-step explanation:
There are two ways to solve this.
Either you can solve by finding the 15% that are late and subtracting that from 900, or you can find the 85% of kids that are not late.
Method One:
15%=0.15
900 x 0.15 = 135
900-135= 765
Method 2:
100-15=85%
85%=0.85
900 x 0.85=765
Either way, you get 765.
