Solution:

128

Explanation:
If we start from the small squares and the move up the scale, we can identify them without a problem.
1x1 squares = 62
2x2 squares = 41
3x3 squares = 18
4x4 squares = 6
5x5 squares = 1

Now, totaling them, we get:
62 + 41 + 18 + 6 + 1 = 128 squares.

Since Jasmine and Thibault ate equal amount, they should pay the same amount. But since that's not possible, they can decide with 'rock, paper, scissor' or an equivalent measure to determine who will pay the extra dollar. Now, let's assume tha Jasmine pays $1 extra after losing

Jasmine will pay $5, Thibault will pay $4 and Noah will pay $2.

If the pizza's cost was $11, we can simply keep the same offset and divide. Jasmine is paying 6% more, Thibault is paying 15% more and Noah is paying 27% more.
Keeping the offset same both Jasmine and Thibault will pay $5 each and Noah will pay $1.
