n! Might be 7, and n might be 6. r might also be 6. So 6 - 6= 0! = 1
So I think it might be 7 ÷ 1, which is 7.
To answer this, first make an equation representing the data:
15+ 0.20X= Bill
now plug in data you know:
15 + 0.20(30)= bill
and finally solve it:
Bill= $21.00

<h3>How to calculate the area between a rhombus and a circle</h3>
According to the description in statement we prepared a representation of the figure in the image attached below. The <em>shaded</em> area is equal to the area of the <em>circle</em> sector (
), in square centimeters:
(1)
Where:
- Length of the radius, in centimeters.
- Angle of circle arc, in degrees.
If we know that
and
, then the area of the circle is:
