for all these 2 state gas law type problems do this
.. (1) start with P1V1 / (n1T1) = P2V2 / (n2T2)
.. (2) rearrange for your unknown variable
.. (3) identify and cancel anything held constant
.. (4) plug in the data, chug out the results... T must be absolute
**********
this problem
.. P1V1 / (n1T1) = P2V2 / (n2T2)
rearranging
.. T2 = T1 * (n1 / n2) * (P2 / P1) * (V2 / V1)
we assume moles is constant, we assume P is constant
.. T2 = T1 * (V2 / V1)
solving... .. note that V2 = 1.3 * V1
.. T2 = (17+273 K) * (1.3 V1 / V1)
.. T2 = (290K) * 1.3 = ___ K = __ °C
you get to finish

17C = 290.15K; the temperature would have to be raised by 30%, so up to 377.2K, or 104C.

Assuming pressure is constant, 30% more volume is 30% more temperature.
New temperature = (17C + 273) * 1.3
