So first let me assume that the Total profit of the racquets are 8 percentage and not individually.
Now to find the profit we can do
20 x 100= 2000
Now
8=x/2000*100
X= 160
And now for loss
10x80=800
Now
15= x/800*100
X=120
Now profit =
160-120 = 40
The profit was only 40
Set measurements equal to each other.
7X + 20 = 8X + 8
-7X -7X
20 = X + 8
-8 -8
ANSWER: X=12
An Infinite Number of solutions is the answer! LMK if you have any more questions, and have a nice day/evening.
Answer:
Step-by-step explanation:
x^2
--------------------------------------------------
2x + 1 / 2x^3 - x^2 + x + 1
2x^3 + x^2
-----------------------
0 + x + 1
x + 1
The quotient is x^2 + ------------
2x + 1
