Answer:
Commas, tabs, semicolon, or spaces. 
Explanation:
In Excel, commas, tabs, semicolon, or spaces are known as delimited values, and you can tell excel which option your data has in order to separate it. For example, if you copy and paste text that will be used for column header you can use the "Text to Columns" tool, click "delimited" and next, and then check the box next to which type of separator you are using (commas, tabs, etc). The tool will then separate every item of text with that type of separator into different columns. 
 
        
             
        
        
        
Answer:
to obtain 10,000 hours of light you would need:
option 1)
10 incandescent light bulbs costing $0.50 each = $5
this incandescent light bulbs will consume 60 x 10,000 = 60,000 watts or 60 kWh = 60 x $0.10 = $6 in electricity
total costs using incandescent light bulbs = $5 + $6 = $11
option 2)
1 fluorescent light bulb = $4
this fluorescent light bulb will consume 15 x 10,000 = 15,000 watts or 15 kWh = 15 x $0.10 = $1.50
total costs using fluorescent light bulbs = $4 + $1.50 = $5.50
