sell 48 tickets at the door.
Step-by-step explanation:
5x+4(40)≥400
1. Distribution; 5x+160≥400
2. Subtract 160 from both sides; 5x+160-160≥400-160
3. you are left with; 5x≥240
4. divide 5 from both sides; 5x/5≥240/5
5. you are left with; x ≥ 48
Meaning; they need to sell 48 or more tickets at the door to reach their goal of $400.
