Answer:
1. The price of old model is 13,578
2.The Length is 64
The Width is 32
Explanation:
Let P= Price
2X=Old Price
NP=New Price
NP – 2X = P
29,078.00 – 2X = 15,500
-2X=15,500 – 29,078.00
-2X= -13,578
-2X/-2 = -13,578/-2
X = 6,789
29,078.00 – 2X = 15,500
29,078.00 – 2(6,789) = 15,500
29,078.00 – 13,578 = 15,500
15,500 = 15,500
The price of old model is 13,578
_______________________________________________
Remember the formula for perimeter 2L+2W=P
Let X = Width
2X = Length
2L+2W=P
2(2X) + 2(X) = 96
4X + 2X = 96
6X = 96
6X/6=96/6
X = 16
2(2X) + 2(X) = 96
2(2*16) + 2(16) = 96
2(32) + 32 = 96
64 + 32 = 96
96= 96
The Length is 64
The Width is 32
