Question

Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing, which inequality represents this situation?

Answer 1

He plays trumpet for a minimum of 45 minutes

45 minutes = 45/60

                  = 3/4 hours

If x is the number of days that Lionel practices then he practises for at least 

3/4 x hours

y is the total number of hours he spends practicing


So, the inequality is:


3/4 x ≥ y

Answer 2

Answer: He plays trumpet for a minimum of 45 minutes

45 minutes = 45/60

= 3/4 hours

If x is the number of days that Lionel practices then he practises for at least

3/4 x hours

y is the total number of hours he spends practicing

So, the inequality is:

3/4 x ≥ y
