suter [353]

Answer:

The expression representing the Total cost of 6 boxes is 6(3t + 2c).

The Simplified expression representing the Total cost of 6 boxes is 18t + 12c.

Step-by-step explanation:

Given:

Number of thriller movies = 3

Number of Comedy movies = 2

Let the cost of thriller movie be t

Also Let the cost of comedy movie be c

Total Number of boxes = 6

Now, given a DVD box set includes 3 thriller movies and 2 comedies.

Cost of Each box = 3t + 2c

We need to find the total cost of 6 boxes

Total Cost of 6 boxes is = 6(3t + 2c)

Hence the expression representing the Total cost of 6 boxes is 6(3t + 2c).

Simplifying the above expression we get;

Total Cost of 6 boxes is = 6(3t + 2c)= 6\times3t+6\times2c=18t+12c

Hence the Simplified expression representing the Total cost of 6 boxes is 18t + 12c.
