Well when you add $84+$29 you get $113
        
             
        
        
        
Let t = total number of cans they collected.
(65/100)t + (2/10)t 
We can now add the two algebraic fractions.
LCD = 100
See picture.

Answer:
Choice A.
Step-by-step explanation:
tan < ABC = 60/40
So m < ABC = 56.31 degrees.
This makes m < DBC = 56.31 / 2 =  28.15 degrees
tan 28.15 = DC / 40
DC = 40 tan 28.15
= 21.407 ft.
