Justin has $7.50 more than Eva and Emma has $12 less than Justin. Together, they have a total of $63.00. How much money does each person need?

IF it's asking for how much money each person has ...

x = eva

x + 7.50 = justin

(x + 7.50) - 12 = emma

therefore ...

x + x + 7.50 + x + 7.50 - 12 = 63

combine like terms ...

3x + 3 = 63

solve for x.

3x = 60

x = 20

therefore, eva has $20.

justin has $27.50

and Emma has $15.50
