Answer:
Jed's Market
Step-by-step explanation:
Find out the cost of one candy bar for each store:
Smith's:
- 9.00 ÷ 3 = $3.00
Green's:
- 10.00 ÷ 4 = $2.50
Jed's:
- 12.00 ÷ 5 = $2.40
Wan's:
- It already tells you the price for each: $2.75
Finding the best deal:
- Look at all our costs per 1 candy bar. Which one has the smallest price?
- Because $2.40 is the smallest price, Jed's Market has the best buy.
I hope this helps!
 
        
             
        
        
        
Answer:

Step-by-step explanation:
        We will use the equation of change in y over change in x to solve for the slope of the line. Then, we will simplify.




 
        
             
        
        
        
That's written as  5.6 x 10⁻¹⁷ .
(To change 5.6 into the original number, you'd need to 
move the decimal point 17 places backwards.)
        
             
        
        
        
Thickness of the plate before polishing = 2.342 
Thickness of the plate after polishing. = 2.087 
How much was removed = 2.342- 2.087 = 0.255
Hence , the answer 0.255 which is option B
