Identify as an increase or decrease. Then find the percent of increase or decrease. If necessary, round to the nearest percent. Original: 170 New: 90 %_

the percent decrease is approximately 47 %

Step-by-step explanation:

Since the quantity started at 170 and then changed to 90, there was clearly a decrease in its value.

We use the following formula to calculate the percent of decrease:

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
