Answer:

See below

Step-by-step explanation:

Each person donates $10 plus the $70 he got must be at least $250.

10x + 70 [tex]\geq[/tex] 250

10x [tex]\geq[/tex] 180

x [tex]\geq[/tex] 18. To get at least $250, 18 people need to contribute.

On the other side:

10x + 70 [tex]\leq[/tex] 350

10x [tex]\leq[/tex]  280

x [tex]\leq[/tex] 28 To get $350, 28 people need to contribute.

Write the entire inequality as 250 [tex]\leq[/tex] 10x + 70 [tex]\leq[/tex] 350
