Question

The value of a professional basketball player's autograph rose 20% in the last year. It is now worth $288.00. What was it worth a year ago?

Answer 1

pls answer

Answer 2

let the value a year ago be x
so given that after rose 20% the value is $288,00

x = ?

Answer 3

using the rule of 3 simple we can calcule the 20% what let be y

x mean 100% so 1
y mean 20% so 0,2

y = 0,2*x

so this mean that x +0,2x = 288

1,2x = 288

x = 288/1,2 = 240

hope this is understandably for you
