Answer:
l=26
w=20
Step-by-step explanation:
l-6=w
2l+2w=92
2l+2(l-6)=92
2l+2l-12=92
4l=104
l=26
(26)-6=w
w=20
Cost of Lightbulb = x
cost of switch is x-8
9x + 4(x-8) = 520.50
Use distributive property:
9x + 4x -32 = 520.50
Simplify:
13x -32 = 520.50
Add 32 to both sides:
13x = 552.50
Divide both sides by 13
X = 42.50
A lightbulb costs $42.50
A switch costs 42.50-8 = $34.50
