Answer 1

Answer:

Step-by-step explanation:

To find the best place to buy the video game, we need to find the price for each store, and see which is least. To do this, find the percents of each and subtract.

To find the percent, simply multiply your original number by a decimal version of the percent

Ex: 160* .4=64

     155*.3=46.5

     160*.2=32.

Then, subtract the amounts from each price.

160-64=96

155-46.5=108.5

160-32=128

Clearly, store a is the best place to buy the system.

Hope this helps!
