natali 33 [55]

Answer:

Evan is correct

Step-by-step explanation:

To find this answer, we can use the formula A=PxW

A=Part, P=Percentage, W=Whole

We can fill in the numbers we know and leave blank (with the variable) the numbers we want to find out

In this scenario, we want to find out if 25 is 125% of 29

So we can use this formula and do the equation like this:

A=1.25x20

This gets us to 25

So Evan is correct!
