Answer 1

200 pounds

Explanation:

We can write a proportion to represent the problem. Let's take x as the weight of 5 televisions. If we know that 4 televisions weigh 160 pounds we can write: 4/160. Then, 5 televisions will weigh x pounds which is 5/x. Now, we can set up a proportion: 4/160 = 5/x

Cross multiply to get: 4x = 800

Isolate x: x = 800/4

Solve: x = 200
