Question

What single decimal multiplier would you use to increase by 7% followed by a 9% increase?​

Answer 1

`Digit = 1.1663`

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:

`x = 1 + 7\%`

Express as decimal

`x = 1 + 0.07`

`x = 1.07`

Increment by 9% is:

`y = 1 + 9\%`

Express as decimal

`y = 1 + 0.09`

`y = 1.09`

The single digit is:

`Digit = x * y`

`Digit = 1.07*1.09`

`Digit = 1.1663`
