Question 281230
Yabbas (Y) are inversely proportional to the number of Dabbas (D).
a)write a general equation that summarizes this relationship.
b)when 51 Dabbas produce 3 Yabbas, what is the constant of proportionality?
c)how many Dabbas would be needed in order to produce 17 Yabbas?

a.) Y = k/D  where k is the constant of proportionality
b.) 3 = k/51
    k = 3*51 = 153
c.) 17 = 153/D
     17D = 153
       D = 9
