M=c•p
multiplying the prince by the number of cars washed will give you the total amount of money the school has raised
Revenue = price * number of backpacks
number of backpacks = -2p + 50
p = 9 ; -2(9) + 50 = -18 + 50 = 32
revenue = 9 * 32 = 288
p = 12 ; -2(12) + 50 = -24 + 50 = 26
revenue = 12 * 26 = 312
<u>p = 12.50 ; -2(12.50) + 50 = -25 + 50 = 25</u>
<u>revenue = 12.50 * 25 = 312.50</u> GIVES THE MAXIMUM REVENUE
p = 15 ; -2(15) + 50 = -30 + 50 = 20
revenue = 15 * 20 = 300
Step-by-step explanation:
3x-y= 1
bring 3x to the right so it become negative
-y= 1 - 3x
divide by -1 for each expression
y = -1 + 3x
arrange it by bring 3x to the front side
y = 3x-1
You can simplify the given expression by taking out those factors who are perfect squares.
The simplified form of the given expression will be 
<h3>How to simplify values which are under the root?</h3>
If possible, try to defactor what is inside the root.
For example, if 8 is under square root, then you can defactor 8 as made up of 2 times 2 times 2. Since 2 times 2 is perfect square, thus this can come out of the root.
Simply, some more such methods can be used to simplify these type of values.
<h3>Using the simplification method on given expression</h3>
Thus, after getting simplified, the expression becomes
