The cost of a book was decreased from 60 to 50 by what percent the price decrased with solution

The price decreased by 16 1/3%, or approximately 16.3%

Step-by-step explanation:

Use the formula for percent change. If the answer is negative, it is a percent decrease. if the answer is positive, it is a percent increase.

percent change = (new price - old price) / (old price) * 100%

In this case, use:

new price = 50

old price = 60

percent change = (new price - old price) / (old price) * 100%

percent change = (50 - 60) / 60 * 100%

percent change = - 10/60 * 100%

percent change = - 1/6 * 100%

percent change = - 100/6% = - 50/3% = - 16 1/3%

The price decreased by 16 1/3%, or approximately 16.3%
