Answer: 34%
Step-by-step explanation:
Given
Price is marked down by 60% with an additional discount of 15% on the marked down price
Suppose x is the original price of the item
After marking down, it is
after additional discount it is
Effective discount on the item is
Thus, a person is paying 
of the original price
Treat
as the boundary of the region
, where
is the part of the surface
bounded by
. We write
with
.
By Stoke's theorem, the line integral is equivalent to the surface integral over
of the curl of
. We have
so the line integral is equivalent to
where
is a vector-valued function that parameterizes
. In this case, we can take
with
and
. Then
and the integral becomes
<span />
In this problem, we have to find the factor which will
make (1 / 10) equal to (2 / 5). Therefore we can write it as:
x (1 / 10) = 2 / 5
where x is the number of people who ate the blueberries
x = (2 / 5) / (1 / 10)
x = 4
<span>Therefore 4 people ate the blueberries.</span>
-sinx + C
