Answer:
Our total amount value is $4.86.
Step-by-step explanation:
The total amount given is $30.
Now 8 % of $30 = 
or, 8% of $30 = $2.4
Now adding $30 and $2.4,
$ 30 + $2.4 = $32.4
Finding 15% of the total $32.4,
we get 
or, 15% of $32.4 = $4.86
hence, our total amount value is $4.86.
Any number is equal to that number over 1
So x is equal to x/1
Same thing with 24. 24 = 24/1
To get it into percent we multiply by 100 so:

And simplifying that we get

And x/100 = x%
so 2400/100 = 2400%
So your answer is
<em><u>2400%</u></em> :)
