Could you show us a picture of the question
Answer:
I'm almost positive it's .A but I'm not sure
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

Answer:
Step-by-step explanation:
A accurate map should be to scale. Scaled distances between features should agree with actual distances. The shapes of objects (eg houses) should be the same as in real life. All road names names and house numbers etc should be displayed.
However, to create such a map would need considerable expertise. It would be unreasonable to expect someone to produce it for a class project.
It would be useful if it was roughly to scale with houses shown in approximate positions and shapes. Names and numbers are essential. It would be useful to show North.
