Let l be the number of CDs Ms. Kitts sold last week, and t be the number of CDs she sold this week.
From the given information, we can write the following equations:
1) l = 3t + 6 (Ms. Kitts sold 6 more than 3 times the number of CDs she sold this week)
2) l + t = 110 (Ms. Kitts sold a total of 110 CDs over the 2 weeks)
Therefore, the system of equations that can be used to find l and t is:
l = 3t + 6
l + t = 110
From the given information, we can write the following equations:
1) l = 3t + 6 (Ms. Kitts sold 6 more than 3 times the number of CDs she sold this week)
2) l + t = 110 (Ms. Kitts sold a total of 110 CDs over the 2 weeks)
Therefore, the system of equations that can be used to find l and t is:
l = 3t + 6
l + t = 110
