A video game store sold 135 copies of a new release game in June. In July, they sold 108 copies of the same game. What is the percent decrease in the sales of this game from June to July?

percent decrease: decrease/old price * 100%

Subtract:

135 - 108 = 27

Fill into formula,

= 27/135 * 100%

= 1/5 * 100%

= 0.20 * 100%

= 20%

therefore, the percent decrease is 20%!

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general
