Victor had 321.8 dollars, Andrey had 15.8 dollars more than Victor had. David had 5 times less than Victor and Andrey had together. How many dollars did each boy have?

Victor: $321.80 Andrey: $337.60 David: $131.88

Step-by-step explanation:

Andrey had $321.80 + 15.80 = $337.60.

We assume "5 times less than" means "one-fifth of", so David had ...

(1/5) ($321.80 + 337.60) = $131.88

The amount each had was ...

Victor: $321.80 Andrey: $337.60 David: $131.88
