Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
To begin solving this question we need to create a formula to then solve. According to the information given in the question we can create 2 formulas.
<u>Where:</u>
- P is the perimeter
- L is the length
- W is the width
Now we can replace L for the L in the P formula and solve for W, Like so....
Now that we have the value of W we can plug that into the L formula and find L
Finally, we can see that the value of the Length is 11.95 in and the Width is 9.95 in

The percent increase from the original cost of the entertainment system to the cost of the entertainment system using the payment plan is 12%.
<u>Step-by-step explanation</u>:
- The original cost of entertainment system = $500
- The cost using payment plan= $125+ ($72.50
6)
- cost by payment plan ⇒ 125+ 435 = $560
Percentage increase = (higher value - lower value/ lower value) 100
⇒ ((560-500)/500) 100
⇒ (60/500) 100
⇒ 0.12 100
⇒ 12%
