Let the retail cost be x and the wholesale cost be y. From the first statement, we can formulate the equation written below:
x = y + 0.45y
x = 1.45y
Therefore, the retail cost is 1.45 times greater than the wholesale cost.
The perimeter is the sum of all the sides, so P = (5x -7) + (3x-4) + (2x -6). Then group like terms so you have p = 5x + 3x + 2x -7-4-6 and end up with P = 10x - 17

14 /1770. that's it if that's what ya needed.
74-34=20 so then y=20 because 20*2+34=74
IN other words
74-34=20
