All but the 3rd one have solution x = 4.4.

_____

a. x = 13×0.3 + 0.5 = 3.9 + 0.5 = 4.4

b. x = 3×1.2 + 0.8 = 3.6 + 0.8 = 4.4

c. x = 5×0.9 + 0.1 = 4.5 + 0.1 = 4.6

d. x = 8×0.4 + 1.2 = 3.2 + 1.2 = 4.4

Reptile [31]

The second constraint is the same as the objective function, so your problem boils down to finding integer solutions to
.. 3x1 +5x2 = 36

There are 3 solutions. They are (x1, x2) = (12, 0), (7, 3), (2, 6)

The value of the objective function there is (obviously) 36.
