a newborn infant usually tripples its birthday weight by its first birthday. baby carter weighed 28 pounds on his first birthday. if this were tripple his birth weight (b), which equation below could be used to determine his birth weight?
1)b/3=28
2)b3=28
3)3b=28
4)b +3=28
5)3(b+3)=28

In other words if baby carter weight from birth is 3 times it when he i his first birthday
birth weight times 3 = how much he weighs his first birthday
