Question

3. Jose began the day with eight Magikarps. After spending the day at the lake, he ended up with sixteen Magikarps.

Answer 1

We can find the percentage of increase in the number of Magikarps that Jose captured in the lake by taking the initial number of them and subtracting it from the number that he had by the end of the day, like this:

16 - 8 = 8

Now, we just have to divide 8 by 16 and then multiply by 100, like this:

$\frac{8}{16}\times100=50$

Then, his number of Magikarps increased a 50%
