It costs Amy $0.20 to send a text message.  She has already spent $5 in text messages this month.  If she has a total of $12 that can spend this month on text messages, write and solve an inequality that will give the greatest number of text messages that she can send.

• 0.20x + 5 = 12;
  85 text messages

• 0.20(5x) = 12; 
  12 text messages

• 0.20x + 5 ≤ 12;
  x ≤ 35 

• 0.20x + 5 ≥ 12;
  x ≥ 35
