Question

if the tire pressure gauge is showing the reading 8% higher, the what is the actual pressure if the reading is 39.42?

Answer 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

$\frac{108}{100}x=39.42\\1.08x = 39.42$

Dividing both sides by 1.08

$\frac{1.08x}{1.08}=\frac{39.42}{1.08}\\x=36.50$

Hence,

The actual pressure is 36.50
