Problema Solution
The total weight of n soccer balls is m ounces. m directly proportionally to n, and n=12 when m=54
Answer provided by our tutors
m directly proportionally to n then there is a non-zero constant k such that
m = k*n
knowing that n=12 when m=54 we find k
54 = k*12
k*12 = 54 divide both sides by 12
k = 54/12
k = 4.5
the weight of one soccer ball is 4.5 ounces.
