12 pounds

Explanation:

Well, it was 8 pounds at birth, and has increased weight by 50% one month later.

50% of 8 is 4

:. The baby's weight increased by 4 pounds.

8+4=12

So, the total weight of the baby is 12 pounds one month later.

12 Pounds

Explanation:

50% means half. So the baby's weight increased by half its original weight.
If it weighed 8 pounds, then half of that is 4 pounds.
Increase means add, so add original weight to the increased weight, so 8+4=12 pounds. Quick Maths.

Here's the equations
1.5*8=12
or
8+0.5*8=12
