Answer:
Katie will collect more than 100 seashells in 5 and a half days.
Step-by-step explanation:
Katie already has 34 seashells in her collection.
Each day, she finds 12 more seashells on the beach.
Let x be the number of days Katie is collecting seashells.
In x days, she will collect 12x seashells.
In total, she will collect [tex]34+12x[/tex] seashells.
Katie wants to collect over 100 seashells, so
[tex]34+12x> 100[/tex]
Solve this inequality. Subtract 34:
[tex]34+12x-34>100-34\\ \\12x>66\\ \\2x>11\\ \\x>5 \dfrac{1}{2}[/tex]
Katie will collect more than 100 seashells in 5 and a half days.
