Question
The pressure of a gas in a container depends on is temperature. An auto mechanic uses the formula above to estimate actual tire pressure, P, in pounds per square inch (psi), given the temperature outside, t, in degrees Fahrenheit, and the pressure, x, in psi to which the tire was originally inflated in a factory environment that is air conditioned to 70°Fahrenheit. Which of the following expressions could be used to determine the approximate temperature outside given a tire’s actual pressure and original inflated pressure?
Options
A
10P-10x+70
B
10P-10x+700
C
10P+10x-70
D
P+10x-70
