Answer:
$25 a lamp
Step-by-step explanation:
First divide $10,000  by 500 lamps to find how much one of them cost
That is $20 a lamp so then multiply .25 *20 or 1/4 *20
you get 5 than add 20 +5=25
 
        
             
        
        
        
To find the total area of this figure, you have to find the area of each of the separate figures and then add those 2 answers together. Your work should look like this:
2 x 2 = 4
8 x 8 = 64
64 + 4 = 68
Your answer should be 68 ft.^2
