Katie wants to collect over 100 seashells. She already has 34 seashells in her collection. Each day, she finds 12 more seashells
dlinn [17]

Answer:

12d+34>100  

Step-by-step explanation:

Let d be the number of days.

We have been that each day Katie finds 12 more seashells on beach, so after collecting shells for d days Katie will have 12d shells.  

We are also told that Katie already has 34 seashells in her collection, so total number of shells in Katie collection after d days will be: 12d+34

As Katie wants to collect over 100 seashells, so the total number of shells collected in d days will be greater than 100. We can represent this information in an inequality as:

12d+34>100

Therefore, the inequality 12d+34>100 can be used to find the number of days, d, it will take Katie to collect over 100 seashells.
