Allison practices her violin for at least 12 hours per week. She practices for three fourths of an hour each session. If Allison has already practiced 3 hours this week, how many more sessions remain for her to meet or exceed her weekly practice goal?

Sessions needed= 12

Step-by-step explanation:

Giving the following information:

Total hours= 12 hours

Practice= 3/4= 0.75 of an hour

Already practiced= 3 hours

First, we need to determine how many minutes does she practice each session:

Minutes per session= 0.75*60= 45 minutes

Now, we divide the total practice in minutes required for the minutes per session:

Sessions needed= (9*60) / 45

Sessions needed= 12
