Answer: 33 1/3%
Step-by-step explanation:
Percentage increase of the shirt will be calculated as:
= Price Increase / Old price × 100%
Price Increase = $20 - $15 = $5
Old price = $15
Percent increase = Price Increase / Old price × 100%
= 5/15 × 100
= 1/3 × 100
= 33 1/3%
 
        
                    
             
        
        
        
Answer:
8. m=6
9.  x=2; Alyssa is incorrect because she subtracted 8 from 16 when in reality she should have divided 16 by 8 to get 2. The real solution is 2 because 8 times 2 is equal to 16. 
Step-by-step explanation:
Question 8: 
2m-6=m
-2m    -2m     (subtract 2m from both sides)
<u>-6</u>=<u>-m</u>  
-       -     (divide both sides by the negative)
m=6
Question 9:
<u>8x</u>=<u>16  </u>              (divide both sides of the equation by 8)
8     8
x=2
