Answer:
Valentina and Laura finished the same total number of shirts in 
 hours.
Total number of shirts finished by Valentina 
Total number of shirts finished by Laura 
Step-by-step explanation:
Suppose that Valentina and Laura finished the same total number of shirts in 
 hours.
Valentina can embroider 2 shirts per hour and Valentina has already completed 15 shirts.
Total number of shirts finished by Valentina 
Laura can get through 3 shirts per hour and Laura has completed 11 shirts.

Total number of shirts finished by Laura 
 
        
             
        
        
        
(x-h)²+(y-k)²=r² is the equation of a circle with radius of r
so if x-h=4 and y-k=3 then
4²+3²=r²
16+9=r²
25=r²
sqrt both sides
5=r
radius is 5 units
        
             
        
        
        
Answer:
3/20
Step-by-step explanation:
1/1-1/4-3/5= (money spent)
1×4×5/(1×4×5)-1×1×5/(1×4×5)-3×1×4/(1×4×5)
20/20-5/20-12/20
(20-5-12)/20=3/20
