Question 7 )

soldier1979 [14.2K]

Answer:

Tony has 45 dollars

Milan has 15 dollars

Lucy has 25 dollars

Explanation:

Let x represent the amount of money Milan has in his wallet.

TONY: 3x

MILAN: x

LUCY: x+10

Lucy, Milan, and Tony have a total of $85 in their wallets. Hence, the following equation.

3x+x+x+10=85

5x+10=85

5x=75

x=75/5

x=15

Tony has 45 dollars (3*15=45)

Milan has 15 dollars (x=15)

Lucy has 25 dollars (10+15=25)
