If my bill is $160 and they’re going to takeoff 25% of the total bill how much money will i give them

You will pay $120

Step-by-step explanation:

There are many methods in solving this percentage equation, but this is by far my favorite. Here is how it works.

1.Take 160, the original amount.         160

2.Then take the percent amount        .25

and convert into decimal.          

3. Multiply the numbers                   40.00

4. Subtract the product from         160

original amount, 160.                  -    40

                                             $120

That is how I would get my answer. I am very sorry if the formatting messes up, but it is this basic problem:     160*.25=40.00 then 160-40=120

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
