A phone on eBay is priced at $400. the following week the same type of phone was priced for $300. what was the percent decrease in price

25 percent. To solve more of these problems put the new price over the original price and you will get the cost of the new object in relation to the original cost. 300/400=.75 which means the new price 1.00-.75=.25 percent drop

If you would like to know what was the percent decrease in price, you can calculate this using the following steps:

x% of $400 is $300

x% * 400 = 300

x/100 * 400 = 300

x * 4 = 300 / 4

x = 300 / 4

x = 75%

100% - 75% = 25%

The correct result would be 25%.
