W=x
L=2x+17
Double everything since we need to lengths and two widths to find the perimeter
2x+17+2x+17+x+x = 76
Combine like terms
6x+34=76
Solve for x
First step is subtract 34 from both sides
6x=42
Next you divide both sides by 6 in order to get x by itself
X=7
Now you plug in 7 into the x’s in length and width
W=7 cm
L=31 cm
THE WIDTH IS 31 CM
Check:
7+7+31+31 = 76 cm
It equals 76 cm just like the problem said so therefore it is right.

Answer:
$267.15
Step-by-step explanation:
The way my math teacher showed me to do it is take the price you paid and multiply it by 1.x (x being the amount of the discount).
In doing that, $205.50 multiplied by 1.30 is $267.15 and the original price of the jersey.
Hope this helps :)
