the value of a professional basketball players autograph rose 30% im the last year. it is now worth 338.00. what was it worth a year ago

Answer 1

Let x = original value

Original value + increase = current value

x + 0.3x = 338

Just need to solve

Combine like terms

1.3x = 338

Divide both sides by 1.3

1.3/1.3x = 338/1.3

x=260, The value of the autograph a year ago is $260
