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.
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.
