Answer 1

let no of children be x and adults be y

thus x+y=13

also  let the cost per head be

   5x+15y=115

   x+y=23

 now from 1 and 2 you can solve the equations by any method

hope this helps

Answer 2

Answer:

let...

the no of children be x

the no of adults be y

x+y =13........eq(i) × 5

5x + 15y = 115 ........eq(ii)

5x + 5y =65.......eq(iii)

subtracting eq iii from eq ii

x = 5

y= 8
