Answer:
55 pounds
Step-by-step explanation:
Add all the differences to the initial weight
55.75+2.125-3.25-0.5+0.875=55
 
        
             
        
        
        
$7.20 per hour, 1.5*$7.20 = $10.80/hour for overtime
40*$7.20 + (44.5-40)*$10.80 = $336.60 in gross earnings
        
             
        
        
        
A) ratio of the perimeters is the same as ratio of corresponding sides, so:
 b) ratio of the areas is equal to k² so:
