ankoles [38]

We know that he weeds gardens for 15 hours, and mows lawns for x hours.

If he wants to earn $252 per month, we can express the following

9\cdot15+9x\ge252

Now, we solve for x

\begin{gathered} 135+9x\ge252 \\ 9x\ge252-135 \\ 9x\ge117 \\ x\ge\frac{117}{9} \\ x\ge13 \end{gathered}<h2>Hence, he has to mow lawns for 13 hours to earn at least $252.</h2>
