Answer: The system of equations for this situation are

l = 3t + 6

I + t = 110

Step-by-step explanation:

Let l represent the number of CDs she sold last week.

Let t represent the number of CDs she sold this week.

Last week she sold 6 more than 3 times the number of CDs that she sold this week. This would be expressed as

l = 3t + 6

Ms. Kitts sold a total of 110 CDs over the 2 weeks. This would be expressed as

I + t = 110
