Traci has four blue pens and three red pens. she has twice as many black pens as blue pens. what fraction represents the number of blue pens out of the total number of pens

No: of blue pens =4
No: of red pens= 3
black pens=twice as many blue pens
                 =2(4)=8
total no: of pens= 4+3+8
                         =14
therefore the fraction required will be =4/15

HOPE THIS HELPS ! :)

What are the options

X= 2 he can buy 2 packs of cards for $12 and an action figure for $3 so he would spend $15 in total plus the free poster
