Cassius Finley · Answer 1

A. 3x+50 ≤ 100; 16 people

Step-by-step explanation:

If x represents the number of people at Berta's party, then the cost of food is 3x. Added to the $50 cost of room rental, the total charge Berta must pay will be ...

3x + 50

She wants this to be at most $100, so her inequality is ...

3x + 50 ≤ 100

Berta can solve this by subtracting 50, then dividing by 3.

3x ≤ 50

x ≤ 16 2/3

Since x represents a number of people, and it is not possible (or desirable) to have 2/3 of a person show up, the maximum number of people that can attend Berta's party is 16.
