Answer:
16
Step-by-step explanation:
Step 1: Figure out how many juniors and seniors there are
50(0.6) = 30 seniors
50 - 30 = 20 juniors
Step 2: Find out how many juniors + seniors stay in the program
30(0.8) = 24 seniors in the after-school program
20(0.4) = 8 juniors in the after-school program
Step 3: Find the difference
24 - 8 = 16
And we have your final answer!
