Every day, katie looks for seashells on the beach. she has 28 shells in her collection. katie finds 12 more shells each day. write an inequality to determine the number of days, dd, it will take katie to collect over 100 shells.

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
