Question 1057225:  An electronics store purchases a certain video game from the manufacturer for $10 per unit. The store sells the game at a mark-up of 80% over the purchase price. You found a coupon, offered in the local newspaper, which will reduce the price by 10%. How much money would the store still profit if you purchased the video game using the coupon? Give your answer as a decimal rounded to the nearest hundredth.

You can  put this solution on YOUR website! The store buys the video game for $10/unit, then marks it up 80% over their cost, adding another $8 to the price. You buy the game at $18 minus 10%, or .9 x 18, or $16.20. The store bought the game in the first place for $10, making their profit $6.20, or 62% over wholesale. ☺☺☺☺
