Answer:

8 home theaters are sold for each $ 500 spent on advertising

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Advertising ($)     1,000 - $ 2,000 - $ 3,000

Home Theaters      16      -    32       -    48

2. How many  home theaters does the company sell for each $500 spent on  advertising?

As we can see in the graph:

16 home theaters are sold when the amount on advertising is $ 1,000

32 home theaters are sold when the amount on advertising is $ 2,000

48 home theaters are sold when the amount on advertising is $ 3,000

Therefore, we can use this ratio:

x = Number of home theaters that are sold when the amount on advertising is $ 500

16/1,000 = x/500

1,000x = 500 *16

1,000x = 8,000

x = 8,000/1,000

x = 8
