Lucky you are not an economist. The 40% increase was for the price of the fuel not the whole excursion. If the fuel component of the whole day was say 20% (generous)then the original fuel component would have been 90000rp. 90000rp plus the 40% increase would equal 126000rp. So add that to the original price of 450000rp and you have the new price of 576000rp.
I guesstimate that a new price of 580000rp would be a fair deal.
