Calculations:
Let the time spent in making the cabinet be t hours.
Now profit made after selling the cabinet is $500-125=\mathrm{}375$
Therefore profit made per hour is $\frac{\mathrm{}375}{t}$
Now it is said that the wood worker should earn at least $25 per hour. Therefore, $\frac{\mathrm{}375}{t}\ge 25$ Now solving the inequality we get, $\frac{\mathrm{}375}{t}\ge 25$ $25t\le 375$ $t\le \frac{375}{25}$ $t\le 15$ Therefore the wood worker should complete the work in 15 hours or less to get at least$25 per hour.
