Alisha bought a collection of 500 old pennies. She chose 20 pennies from the collection and recorded their dates. Seven pennies had dates earlier than 1980.

What percent of the pennies in Alisha's collection have dates earlier than 1980?

How would I solve this or what do I do? I'm very confused

500 pennies bought

chose 20

7 were earlier than 1980

7/20 in the sample

I'm not sure of the collection but it be assumed

that because 500 = 20*25 then 7/20 * 25/25

= 7*25/500 pennies in the collection
