Answer:

The final price is $ 22.68 And Proportional constant is 1.4

Explanation:

Given as :

The Original price = $ 16.20

The rate of increase = 40%

Let The final price = x

Now,

Final price after increase = initial price × ( 1 +
$(\textrm Rate)/(100)$

Or. Final price after increase = $ 16.20 × ( 1 +
$(\textrm 40)/(100)$

Or, Final price after increase = $ 16.20 × ( 1.4 )

∴ Final price after increase = $ 22.68

Now , Proportional constant =
(22.68)/(16.20)

I.e Proportional constant = 1.4

Hence The final price is $ 22.68 And Proportional constant is 1.4 Answer
