The actual pressure in the tyre will be 36.5 units.
The complete question is as below:-
Sue's tyre pressure gauge shows a reading which is 8% higher than the actual pressure. what is the actual pressure when Sue's gauge shows 39.42? show how you got the answer.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The actual pressure will be calculated as:-
39.42=(100%+8%)=108%
Let the actual pressure is x=100%. So actual pressure will be:-
39.42/x = 108 / 100
x = ( 39.42 ) x ( 100/108 )
x = 36.5
Therefore the actual pressure in the tyre will be 36.5 units.
