Quotient of a number and 7 = 7N
Reciprocal = 1/7N
(6)(1/7N) = 6/7N
Assume the radius is R.
2*pi*R = 28 -> R = 14/pi
So the area will be pi*R^2 = 196/pi
(-3,-2)
You just change the signs
2.75 x 100 / .20 = 13.75
double check
$13.75 x 0.25 = $2.75
so answer
The bill was $13.75 <span>for lunch before the tip added</span>
