PREVIOUS MATH MADNESS SOLUTION(S)


 

Solution for the last Math Madness question; 5/6/19:  D) 24

 

Use the formula for inverse variation:  b1c1 = b2c2    to find the value of c.

 

Substitute:

 

b1c1 = b2c2

 

(12)(96) = 48c2

 

1152 = 48c2

/48        /48

 

24 = c2

 

Therefore, when b = 48, c = 24
