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%?
[tex]x=\frac{153\ cards *100}{764 \ cards}\\ \\[/tex]
x= 20%
Shannon sold the 20% of her cards
the percent of change in the number of Shannon's baseball card collection is 20%
Have a fantastic day
