Answer:
28 + 12 x ≥ 100
Step-by-step explanation:
Given :
Katie has 28 shells in her collection.
She finds 12 more shells each day.
To Find : an inequality to determine the number of days, dd, it will take Katie to collect over 100 shells.
Solution :
She already had 28 shells
Let the number of days, it will take Katie to collect over remaining shells to make the no. of shells she had over 100 shells be x
She collects shells each day =12
She collects shells in x days =12x
So, inequality to determine the number of days, it will take Katie to collect over 100 shells.
⇒28 + 12 x ≥ 100
Hence an inequality will be 28 + 12 x ≥ 100
