Answer:

vanilla=$5 and fruit juice=$3

Step-by-step explanation:

let $x and $y denote the cost of vanilla thickshake and fruit juice respectively.

Now,

$x=$y+2$ (Given)-----(i)

3×$x + 5×$y =30

3×($y+$2)+5×$y=30 (From equation i )

3×$y +$6 + 5×$y = 30

8×$y + $6 = $30

8×$y= $24

.: $y =$3

Then,

From i

$x =$y+$2

=$3+$2

#$5
