Question

yoko,carlos,and milan have a total of $106 in their wallets. milan has 3 times what yoko has. carlos has $9 less than yoko. how much does each have?

Answer 1

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 =
`(115)/(5)` = 23

thus Yoko has $23, Carlos has $23 - $9 = $14and Milan has (3 × 23) = $69
