Question

A newborn baby's weight increased by 50% in one month. If the baby weighed 8 pounds at birth, how much did it weigh one month later?

Answer 1

`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.

Answer 2

`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`
