  1. Answer:

    The actual pressure is 36.50

    Step-by-step explanation:

    Given that:

    Tire pressure reading = 8% higher

    Reading = 39.42

    As 100% will be the actual reading.

    New reading = (100+8)% = 108%

    Let,

    x be the actual pressure of the tire

    108% of x = 39.42

    [tex]\frac{108}{100}x=39.42\\1.08x = 39.42[/tex]

    Dividing both sides by 1.08

    [tex]\frac{1.08x}{1.08}=\frac{39.42}{1.08}\\x=36.50[/tex]

    Hence,

    The actual pressure is 36.50
