Answer 1

30

Explanation:

technology types:

- rear projection

- LCD

- DLP

- CIT

- plasma

screen types:

- full screen

- wide screen

sizes:

- 13 inches

- 19 inches

- 27 inches

calculate the total number of options by multiplying the number of choices in each category:

total options = (number of technology types) * (number of screen types) * (number of sizes)

total options = 5 (technology types) * 2 (screen types) * 3 (sizes)

total options = 5 * 2 = 10 * 3 = 30

total options = 30

the store has 30 different televisions for you to choose from.
