Hello, sorry can’t help with that. i guess that’s just the way you are.
A function means every value of x only has 1 y value.
So, this is not a function.
You can simply use a calculator (or a piece of paper and pencil!) for this equation, which is nice since it’s easy once you know how :)
To find a percentage of a number, we’ll need to multiply.
12.4% x 57.5 = 7.13
Therefore 12.4 percent of 57.5 is equal to 7.13.
Hope this helps you! :)
