-Ms. Kitts works at a music store. Last week she sold 6 more than 3 times the number of CDs that she sold this week. Ms. Kitts sold a total of 110 CDs over the 2 weeks. Which system of equations can be used to find l, the number of CDs she sold last week, and t, the number of CDs she sold this week?
show step in order
Let's assume that l represents the number of CDs she sold last week, and t represents the number of CDs she sold this week.
According to the given information, last week she sold 6 more than 3 times the number of CDs she sold this week. So the equation for the number of CDs sold last week would be:
l = 3t + 6
Also, it is mentioned that Ms. Kitts sold a total of 110 CDs over the 2 weeks. So the equation for the total number of CDs sold would be:
l + t = 110
Therefore, the system of equations that can be used to find l and t is:
l = 3t + 6
l + t = 110
