Rom, I think that you have made an error.

Dominic paid \$18.90 plus some more.

They each have to pay 1/3 each.  It is easier to think of this as 3/9 each.

But Bob pays 4/9  and Clement pays 5/9

bob pays 3/9 for himself and 1/9 for Dominic.  Clement pays 3/9 for himself and 2/9 for Dominic.

This means that Dominic owes Bob 1/9 of the total and Clement 2/9 of the total

Dominic repays \$18.90 to Clement.  This represents 2/9 of the total.

So 1/9 of the total must be 18.90/2 = \$9.45

So the whole cost must have been \$9.45*9=\$85.05

Clement paid \$18.90 which was 1/3 of the cost of the gift.

The gift costs 3x\$18.90=\$56.70
