Answer:
94
Step-by-step explanation:
Add units together. 87+93+102=282.
Divide total number by number of days. 282/3=94
Ok so first you will need 3 bags since 12*2 is 24 that wont be enough for the whole class so 12*3= 36 so now that we figured out how many bags we need now we have to multiply $8.00 by three the answer is $24
