The work done is calculated using the formula $W = Fd \cos(\theta)$, where $W$ is the work done, $F$ is the force applied, $d$ is the distance moved, and $\theta$ is the angle of the force with the horizontal. Here, $F = 95$ pounds, $d = 5$ feet, and $\theta = 10^\circ$. Thus, $W = 95 \times 5 \times \cos(10^\circ) \approx 467.78$ ft-lb.
