Ms. Kitts works at a music store. Last week she sold 6 more than 3 times the number of CD's 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 CD's she sold this week

Answer 1

This week x.

Last week 3x+6

4x+6=110

4x= 104

X=26

3*26+6=78+6=84 last week

26 this week

110 altogether
