A baby weighed 7.25 lb at birth. At the end of 8 months, the baby weighed 2 1/2 times its birth weight. How many pounds did the baby weigh at the end of 8 months?
A. 14.5 lb
B. 9.75 lb
C. 18.125 lb
D. 14.125 lb
So...
A baby weighed 7.25 pounds at birth (When they were born basically)
When the baby had more than 8 months old, the baby weighed 2.5 times as its birth weight.
How many pounds did the baby weight at the end of 8 months??
I think that you would probably have to multiply 7.25*2.5
