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
Murrr4er [49]

Answer:  \left \{ {{l=3t+6} \atop {l+t=110}} \right.

Step-by-step explanation:

Let be "l" the number of CDs Ms.Kitts sold last week, and "t" the number of CDs she sold this week.

You need to remember that:

1. The word "times" indicates a multiplication.

2. The word "more" indicates addition.

Then, the sentence "Last week she sold 6 more than 3 times the number of CDs that she sold this week" can be represented with equation:

l=3t+6

According to the information given in the exercise, the sum of the number of CDs Ms. Kitts sold last week and this week is: 110 CDs.

Since a sum is the result an Addition, you can write the following equation:

l+t=110

Therefore, the System of equations that can be used to find the number of CDs she sold last week and the number of CDs she sold this week, is:

\left \{ {{l=3t+6} \atop {l+t=110}} \right.
