Answer:
See below
Step-by-step explanation:
Add 46 + 48 + 50 + 52 + 54 + 56 + 58 + 60 + 62 and divide it by 2. That’s the average for the fifth graders.
Add 60 + 62 + 64 + 66 + 68 + 70 + 72 + 74 + 76 and divide it by 2 that’s the average for the eleventh graders.
Then, subtract the two averages. That’s the answer :)
