Each of the members must raise at least $69.46.
To start they need to raise $552.50. However, they have already raised 12% of it. They only need to raise 88% of it.
552.50 x 0.88 = 486.2
Divide the remaining amount by 7 to determine how much each individual must raise.
486.2 / 7 = 69.46
        
             
        
        
        
ANSWER
The correct answer is C
EXPLANATION
We want to find the quotient:

We multiply by the reciprocal of the second fraction:

We cancel out the common factors to obtain:

We multiply to get

This simplifies to :

The volume of the composite figure is the third option 385.17 cubic centimeters.
Step-by-step explanation:
Step 1:
The composite figure consists of a cone and a half-sphere on top. 
We will have to calculate the volumes of the cone and the half-sphere separately and then add them to obtain the total volume.
Step 2:
The volume of a cone is determined by multiplying  with π, the square of the radius (r²) and height (h). Here we substitute π as 3.1415.
 with π, the square of the radius (r²) and height (h). Here we substitute π as 3.1415. 
The radius is 4 cm and the height is 15 cm.
The volume of the cone :
 cubic cm.
 cubic cm.
Step 3:
The area of a half-sphere is half of a full sphere. 
The volume of a sphere is given by multiplying  with π and the cube of the radius (r³).
 with π and the cube of the radius (r³).
Here the radius is 4 cm. We take π as 3.1415.
The volume of a full sphere  cubic cm.
 cubic cm.
The volume of the half-sphere  cubic cm.
 cubic cm.
Step 4:
The total volume = The volume of the cone + The volume of the half sphere,
The total volume  cub cm. This is closest to the third option 385.17 cubic centimeters.
 cub cm. This is closest to the third option 385.17 cubic centimeters.
 
        
             
        
        
        
3/2 is the answer
i say this because you have to think of the problem as 
4y=6x
divide the 4
y=6x/4
simplify
3/2
