Ben has a collection of 240 baseball cards. Of these cards, 30% once played
for the Atlanta Braves, 25% once played for the Texas Rangers, and the rest
played for the Houston Astros. How many of the baseball cards were
players from the Houston Astros?

Respuesta :

Ok so lets start off with calculating the percentage. We have 240 cards so lets find 25% of them so lets use 240 times .25 we get 60 cards then take away 240 - 60 = 180. Next we do the 30% so 240 times .30 would be 72 so take away 180 from 72 thats 108. So there are 108 Houston Astros Cards.
