he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.

$15x+57 \geq 129$

And we have to solve this inequality for x.

First we subtract 57 to both sides. And on doing so , we will get

$15x\geq 72$

Dividing both sides by 15.

$x \geq 4.8$ \
