Answer:

B. 5.81

Step-by-step explanation:

So to get this answer, you'd first find how much square inches are on the cheese. We know its 9/10 of the pizza and the pizza is 215 square inches. To find out what is 9/10 of the pizza you'd multiply 215 by 9 then divide by 10. That'd leave you with 193.5 then you multiply that by the cost $0.03 then get 5.805 which rounds up to 5.81.

lara [203]
Janice bought 3 boxes.

Each box has 6 juice pockets. However, there are 15 players on the soccer team. Two boxes would not be enough, since that would only total 12 juice packets.

So, Janice has to buy 3 boxes, which is 18 juice packets.
