Yoko = $23, Carlos = $14 and Milan = $69
let y represent the amount Yoko has then
Carlos = y - 9 → ( 9 less than Yoko) and
Milan = 3y → ( 3 times as much as Yoko)
the total amount is 106 thus
y + y - 9 + 3y = 106
5y - 9 = 106
add 9 to both sides
5y = 106 + 9 = 115
divide both sides by 5
y = [tex]\frac{115}{5}[/tex] = 23
thus Yoko has $23, Carlos has $23 - $9 = $14and Milan has (3 × 23) = $69
