Step-by-step explanation:

Hello

to solve this problem  we can use a rule of three

Let

the total cards Shannon had  is  100%

so

765   Cards ⇒ 100%

Now, she sold 153 cards

using a rule of three ,it is posible to find the percent of change

Let

765  ⇒ 100%

153   ⇒ x%?

\(x=\frac{153\ cards *100}{764 \ cards}\\ \\\)

x= 20%

Shannon sold the 20% of her cards

the percent of change in the number of Shannon's baseball card collection is  20%
