David has 4 less than one-half the number of balloons that Katie has. If David has d balloons, and Katie has k balloons, which of the following equations correctly expresses the relationship between \(d\) and \(k\) ?
(A)\(d = \frac { 1 } { 2 } (k + 4)\) (B)\(d = \frac { 1 } { 2 } (k - 4)\) (C)\(d = \frac { 1 } { 2 } k + 4\) (D)\(d = \frac { 1 } { 2 } k - 4\) (E)\(d = 2 (k - 4)\)
D
