What is the total cost of 6 box sets.

Question

A DVD box set includes 3 thriller movies and 2 comedies. Use t to represent the cost of each thriller and c to represent the cost of each comedy. Write and simplify an expression that represents the total cost of 6 box sets.

Answer 1

Total cost of 6 sets = 6(3t +2c) = 18t +12c

where t = cost of one thriller DVD

and c = cost of one comedy DVD

one set = 3 thriller and 2 comedy DVD's

cost of one set = 3t+2c

cost of six sets = 6(3t+2c) = 18t+12c

C(6) = 18t +12c
