We need the parenthesis around 15 + 3
Answer is C.
(15 + 3) / 3 = 6
18 / 3 = 6
6 = 6
So the answer is C :)
.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...;)
If we call the number "x" then:
x*25%=21
x*25/100=21
x=21*4
x=84
Hope this helps. :)
