Answer 1

Answer:

The value of basketball player's autograph a year ago is $280

Step-by-step explanation:

Given as :

The present value of autograph = $ 336.00

The rate of increase of autograph = 20%

The time period = 1 year

Let The value one year ago = $ x

So ,

The value of autograph after n year = The present value × $(1+\frac{Rate}{100})^{n}$

Or, $ 336.00 = $ x × $(1+\frac{20}{100})^{1}$

Or, $ 336.00 = $x × 1.2

∴ x = $\frac{336.00}{1.2}$ = $280

Hence The value of basketball player's autograph a year ago is $280 Answer
