Since you are looking for the dollar per hour, can just set the equation up as dollar divided by hour (dollar/hour). You take how much was made ($173.70) and divide it by the hours worked (18 hours).
$173.70/18 = x (x representing how much he makes an hour).
$173.70/18 = $9.65.
Cameroon makes $9.65 an hour.
