Answer

Explanation:

Step1: Calculate the amount of decrease

$136 - 85=51$

Step2: Calculate the percent of decrease

The formula for percent of decrease is $\frac{\text{amount of decrease}}{\text{original amount}}\times 100%$. So, $\frac{51}{136}\times 100%$. $\frac{51}{136}\times 100% = 0.375\times 100%=37.5%$

Answer:

$37.5$
