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

since "c" is the cost of each comedy movie we are going to multiply it by 2. so it equals to 2c. we can use "t" to represent the variable for the cost of each thriller movie. so it equals to 3t. to find the total cost you need to add. so the simplest expression is 3t + 2c
