Answer:
[tex]Digit = 1.1663[/tex]
Step-by-step explanation:
Given
Increase by 7% followed by a 9% increase
Required
Represent by a single decimal
Represent 7% increment by x and 9% increment by y.
Increment by 7% is:
[tex]x = 1 + 7\%[/tex]
Express as decimal
[tex]x = 1 + 0.07[/tex]
[tex]x = 1.07[/tex]
Increment by 9% is:
[tex]y = 1 + 9\%[/tex]
Express as decimal
[tex]y = 1 + 0.09[/tex]
[tex]y = 1.09[/tex]
The single digit is:
[tex]Digit = x * y[/tex]
[tex]Digit = 1.07*1.09[/tex]
[tex]Digit = 1.1663[/tex]
