Answer:
9-3x=0 & 2x+4=10
Step-by-step explanation:
9-3(3)=9-9=0
3x+1=3(3)+1=9+1=10, not 9
9x-1=9(3)-1=27-1=26, not 4
2x+4=2(3)+4=6+4=10
5x-7=5(3)-7=15-7=8, not 1
You need 1500, each box contains 252.
Divide to find the number of boxes you need:
1500 / 252 = 5.95 boxes.
This means you need to buy 6 total boxes.
Each box cost $30.
Multiply the number of boxes needed by $30:
6 x $30 = $180 total.
