<h3>
What is inequlaity?</h3>
In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol.
Given
Samuel is running a 3-mile race.
He would like to finish the race in under 33 minutes.
He has already run for 10.5 minutes.
Let, x be the number of the minutes left for the race.
The inequality represent the situtation is;

Hence, the inequality represent the situtation is 10.5 + x < 33.

Answer: 6th month
Step-by-step explanation:
Let the month where the plans cost the same be represented by x.
Plan A charges $99 for the phone plus $25 per month. This can be written as:
= 99 + 25x
Plan B charges $39 for a phone and a $35 per month. This can be written as:
= 39 + 35x
We then equate both equations and this will be:
99 + 25x = 39 + 35x
Collect like terms
99 - 39 = 35x - 25x
60 = 10x
x = 60/10
x = 6
The plan will cost the same in the 6th month.
