Auto Inflate

Help with chemistry about temperature and pressure?

An auto tire is inflated to 27 lb/in² at a temperature of 27C, after driving a while, the new pressure is taken as 34 lb/in² find the temperature inside the tire. (assume V= constant)

Recall: (P1V1)/T1 = (P2V2)/T2

Since V is constant use P1/T1 = P2/T2

The beginning pressure and temperatures are the P1 and T1 respectively, the final ones are the 2′s.
