Question

More than 600 students travelled to a botanical garden for a college trip. The college allowed 7 students to travel by bike & the rest students on 12 buses, each of which held the same number of students. If there were x students in each bus, which inequality best represents this situation?

• A. 12x + 7 > 600
• B. 12x + 7 < 600
• C. 7x + 12 > 600
• D. 7x + 12 < 600

Answer 1

The correct option is A 12x + 7 > 600

We can model this inequality as follows, students traveling by bus + students traveling by bike > 600

We know that number of students travelled by bike is 7

Number of buses is 12 and there are x students per bus.

So, 12x students travelled by bus. The inequality that best models the situation is 12x + 7 > 600
