Question

The height of a stack of DVD cases is in a proportional relationship to the number of cases in the stack. A stack of

6

cases and its height are shown. Find the constant of proportionality. Then use the constant of proportionality to find the height of a stack of

14

cases.

Answer 1

let h = height of 6 cases

then h=6k

k=h/6 = the constant of proportionality

height of 14 cases = 7h/3

H=14k= 14(h/6)=7h/3
