Which inequality can Josh use to determine x, the minimum number of visits he needs to earn his firs free movie ticket? A 3.5x+15≥553.5x+15\ge553.5x+15≥55 B 3.5+15x≥553.5+15x\ge553.5+15x≥55 C 3.5+15x ≤ 553.5+15x\ \le\ 553.5+15x ≤ 55 D 3.5x+15 ≤ 553.5x+15\ \le\ 553.5x+15 ≤ 55

Accepted Solution

A:
Answer:Option A. 3.5x + 15 ≥ 55Step-by-step explanation:Points Rosh received for becoming a member = 15Points Rosh received for visiting the moving theater = 3.5Total points needed for a free movie ticket = 55For each visit he receives 3.5 points, so for x visits he will receive 3.5x points.Total points = Points received on becoming a member + Points received on x visitsSo,Total Points = 15 + 3.5xThese points must be at least 55 for a free movie ticket. At least means equal to or greater than. So the total points must be equal to or greater than 55 in order to earn a free movie ticket. This can be expressed as:3.5x + 15 ≥ 55So, option A gives the correct answer
