-----
Use a proportion:
sugar/price = sugar/price
-----
?/y = x kg/99
----
# of kg of sugar = y(x/99)kg = (xy/99)kg

She buys +x%2F99+ kg/cents
-------------------------
That means she is buying +%28+x%2F99%29%2F+1+ kg/cent
--------------------------
That means she buys +x+%2B+x%2F99+ kg for
+99+%2B+1+ cents, or $1
----------------------------
With +y+ dollars, she can buy:
+y%2A%28+x+%2B+x%2F99+%29+=+x%2Ay%28+1+%2B+1%2F99+%29+ kg
+x%2Ay%28+1+%2B+1%2F99+%29++=+%28100%2F99%29%2Ax%2Ay+
