Question

One quarter of Steve's baseball cards are from his dad's collection. Another 0.2 are from his uncle , and 0.5 are from his brother. The rest are from Steve's cousin. Thirty of the cards from his cousin are National League players; the other half are American League. How many cards are in his collection?

Answer 1

.25+ .2 +.5= .95 so cousins cards make up 5% so 30 cards is half of that so that make 30 cards 2.5%. So 2.5 x 40 = 100% and 30 x 40=1200..... So Steve has 1200 baseball cards...... Hopefully I'm right... it just feels like it too much cards...;)
