Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Scott has already collected 3 cans but wants to collect at least 12 cans in all.
The inequality to show the number of cans that Scott needs to collect to reach his goal will be:
x + 3 ≥ 12
x ≥ 12 - 3
x ≥ 9
To each his goal, he has to collect at least 9 more cans.
