Step-by-step explanation:
£0.13 = 1 Chinese yuan
£314 =
×1 Chinese yuan
= 2415 Chinese yuan (rounded off to nearest yuan)
Make a change of coordinates:


The Jacobian for this transformation is

and has a determinant of

Note that we need to use the Jacobian in the other direction; that is, we've computed

but we need the Jacobian determinant for the reverse transformation (from

to

. To do this, notice that

we need to take the reciprocal of the Jacobian above.
The integral then changes to

I think it would be 16.95 Hope this help you in someway.
