The work done is 1425 J

Explanation:

The work done by a force to move an object is given by

$W=Fd cos \theta$

where

F is the magnitude of the force

d is the displacement

$\theta$ is the angle between the direction of the force and of the displacement

For the suitcase in this problem, we have:

F = 95.0 N is the force applied

d = 15.0 m is the displacement

$\theta=0$ , since the force is parallel to the displacement

Substituting, we find

$W=(95.0)(15.0)(cos 0)=1425 J$
