Carly practices her butterfly stroke for 3 hours a day, 4 days a week, and her backstroke for 2 hours a day, six days a week. How much time does she spend practicing swimming in a month with 4 weeks?
First find the total time Carly practices the butterfly stroke in a week: 3 hours/day * 4 days/week = 
<gadget id="calculator">3*4</gadget>
<output>12</output>
12 hours/week.
Then find the total time Carly practices the backstroke stroke in a week: 2 hours/day * 6 days/week = 
<gadget id="calculator">2*6</gadget>
<output>12</output>
12 hours/week.
Then add those two amounts of time to find her total practice time each week: 12 hours/week + 12 hours/week = 
<gadget id="calculator">12+12</gadget>
<output>24</output>
24 hours/week.
Then multiply her weekly practice time by the number of weeks in a month to find her monthly practice time: 24 hours/week * 4 weeks/month = 
<gadget id="calculator">24*4</gadget>
<output>96</output>
96 hours/month.
