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

Answer 1

assume Justin has x dollars, so Eva has x-7.5, Emma has x-12,

So,

x + (x-7.5) + (x-12) = 63

3x = 82.5

x=27.5

So, Justin has 27.5, Eva has 20, Emma has 15.5
