The statement that can be put in the blank to make the statement true would be 30 X 10^5 or you can also write this expression as 3.0x10^6.
Answer:
9-4/5
5/5 = 1
Step-by-step explanation:
Suppose x quarts of the 50% solution
0.5x+0.2*20=0.4(x+20)
0.5x+4=0.4x+8
0.1x=4
x=40
We need to find the difference first. 65 - 60 = 5. Now we must find what percent 5 is of 65. It is 7,7%. The number decreased, and so it is a 7,7% decrease.
Price per box, P = $1.45 .
Money left, M = $1247 - $472.70 = $774.3 .
Let, number of boxes are x.
So,

Therefore, they have to sell 534 more boxes.
Hence, this is the required solution.
