Question

The value of a professional basketball player's autograph rose 40% in the last year. It is now worth $294.00.

Answer 1

I'll assume you're asking for the initial price

Let's use x to represent it
The initial price plus 40 percent of that is $294

Let's write that out mathematically

x + (40/100)x = 294
x + 0.4x = 294
1.4x = 294
x = 210

The initial price is $210
