The inequality is  ![6x+4,885.78\leq 9,750.05](/tpl/images/0007/7048/b06b1.png)
 Â
Step-by-step explanation:
Let
x -----> amount of water that can be used by only one family member for the rest of the month
we know that
![6x+4,885.78\leq 9,750.05](/tpl/images/0007/7048/b06b1.png)
Solve for x  Â
Subtract 4,885.78 both sides
![6x\leq 9,750.05-4,885.78](/tpl/images/0007/7048/0fd1e.png)
![6x\leq 4,864.27](/tpl/images/0007/7048/806e5.png)
Divide by 6 both sides
  Â
 ---> maximum amount of water that can be used by only one family member for the rest of the month                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   Â
