At the local video game store, a popular game went from $120 to $85 in a weeks time. What is the percent decrease of the item? R

Svetllana [295]

Answer: 29%

Step-by-step explanation:

The game went from the price of $120 to $85.

In calculating percentage decrease, use the following formula:

= (New Price - Old price) / Old price

= (85 - 120) / 120

= -35 / 120

= -29%

<em>Price therefore decreased by 25%</em>
