Suppose you inflate the tires on your car to 35 pounds per square inch (psi) on a warm fall day in Minnesota (27.0°C, or about 80°F). The next day the temperature plunges to -10.0°C (about 14°F). What is the resulting pressure in your tires? Assume that the volume of the tires remains the same.

a. 30.7 psi
b. 35.0 psi
c. 37.6 psi
d. 42.2 psi
e. 26.8 psi
