Remember that the percent change formula is (difference/original) x 100 and that in a percent decrease, the original value will be the larger of the two numbers.

160 - 152 = 8 is the difference.

Divide that value by the larger of the two values 160. 8 ÷ 160 = .05.

Multiply .05 by 100 to find that the percent decrease is 5%.

Percent increase = (100)(old value-new value)/old value
= (100)(160 - 152)/160
= (100)(8)/160
= 800/160
= 80/16
= 5%

Answer: 5%

Cheers,
Brent
