In this question a vital information has been provided. This information can be used for determining the answer to the question that is asked. It is given that 120% of a certain number is 360 pound. The 100% value of the number needs to be determined.
Let us assume the number to be = x
Then
120x/100 = 360
12x/10 = 360
12x = 360 * 10
12x = 3600
x = 3600/12
= 300
Now we can say that the 100% of the number or the actual number is 300 pounds. I hope the problem is clear to you and you can understand the trick involved in the question.
Answer:
3y=4x
y=4x/3
4x/3=x+3
x/3=3
X=9
y=12
(9,12) this is the answer
Answer: 
Step-by-step explanation:
You know that Josh's base salary is:
And, according to the information given in the exercise, Josh makes $70 more for every copy he sales.
Knowing this you can determine that his total pay will be the sum of his base salary and the podruct of $70 and the number of copies.
Therefore, if Josh sells 22 copies, then we get that his total pay is:

three, twelve, five, and six
A) F(3)=3^2-3:3= 9-3:3=9-1=8
B) ?
C) F(11)= 11^2-3:3=121-1= 120
I think this
