Carolyn practices the piano for 20 minutes a day and the violin for three times as long. If she practice six days a week, how many minutes does she spend practicing in a month with four weeks?
First find Carolyn's total violin practice time by tripling her piano practice time: 20 minutes/day * 3 = 
<gadget id="calculator">20*3</gadget>
<output>60</output>
60 minutes/day.
Then find the total amount of time she spends practicing each day: 60 minutes/day + 20 minutes/day = 
<gadget id="calculator">60+20</gadget>
<output>80</output>
80 minutes/day.
Then find the total time she spends practicing each week: 80 minutes/day * 6 days/week = 
<gadget id="calculator">80*6</gadget>
<output>480</output>
480 minutes/week.
Then find the total time she spends practicing each month: 480 minutes/week * 4 weeks/month = 
<gadget id="calculator">480*4</gadget>
<output>1_920</output>
1920 minutes/month.
