Answer 1

Answer is above mentioned.

Answer 2

Hey!
Your answer is here
_________________
Let the cost of the student meal be x.

$adult \: meal = 28 \times \frac{3}{2}x \\ = 42x$
$student \: meal = 47x$
ATQ

42x + 47x =1424
89x = 1424
x=1424/89
x=16

Therefore, An adult meal costs= 42x = 42×16= 672

A single adult meal costs= 3/2 × x
= 3/2×16
=24
