Each month Ms. Tanaka is paid a base salary of $2,500 in addition to $100 for each television that she sells. This modeled by 2.500 + 100t, where r represents the number of televisions. Evaluate for t = 12 to find how much Ms. Tanaka will earn for selling 12 television this mouth

To calculate Ms. Tanaka's total earnings for selling 12 televisions, we will use the formula given:

\[
\text{Total Earnings} = 2500 + 100t
\]

where \(t\) represents the number of televisions sold.

Substituting \(t = 12\):

\[
\text{Total Earnings} = 2500 + 100 \cdot 12
\]

Calculating \(100 \cdot 12\):

\[
100 \cdot 12 = 1200
\]

Now, add that to the base salary:

\[
\text{Total Earnings} = 2500 + 1200 = 3700
\]

Therefore, Ms. Tanaka will earn **$3,700** for selling 12 televisions this month.

The correct answer is **$3,700**.
