    B. 65.84

    Step-by-step explanation:

    You are given the armspan and a relation between that and height. Put the given value in the equation and solve for the unknown.

    ... 67.5 = 1.123x - 6.443

    ... 73.943 = 1.123x

    ... 73.943/1.123 = x = 65.84

    Riley's height is predicted to be 65.84 inches.
